NSFW accounts follow you because your handle entered a scraped target list, not because of anything you posted about. Follow-bot networks need every account they operate to accumulate outbound follows, and they pull the handles to follow from whatever is currently visible on X.
That is the whole mechanism. The rest of this explains how to read the pattern and what to do about it.
What is actually happening when NSFW accounts follow you.A network operating thousands of accounts needs each one to follow somebody, continuously.Its target lists come from trending queries, high-impression posts, and reply threads under large accounts.Your handle enters that pool when something of yours gets distribution, and leaves it a few days later.The follows arrive in a cluster because one scrape feeds the whole fleet at once.
Circleboom reads your full follower list through official X API access, scores every account on activity, follow ratio, account age and profile completeness, then isolates the flagged segment for review. Start with NSFW accounts following you on Twitter.
Why the timing is always the same
Ask anyone who has been through this and the story matches: a post did unusual numbers, and roughly 24 to 48 hours later the follower notifications changed character.
The delay is the scrape cycle.
A network does not watch X in real time, it harvests periodically, and your handle sits in the harvested list until the next refresh replaces it. So the arrival is batched rather than continuous, and it stops on its own once you drop out of the pool.
That explains two things people find confusing. First, why it feels targeted when it is not: a batch of forty accounts arriving in one hour reads as an attack, but it is one list being processed. Second, why it stops without you doing anything: you did not defeat it, you simply stopped being visible enough to stay in the list.
It also explains why it comes back. Every time you get distribution, you re-enter the pool. Why am I all of a sudden getting new followers covers the same pattern from the notification side.
Why NSFW accounts specifically, and not other kinds of spam
The concentration is measurable rather than anecdotal. Pew Research Center analysed which links on the platform came from accounts showing bot-like characteristics and split the results by content category.
Adult content led every other category at 90 percent, ahead of sports at 76 percent and news and current events at 66 percent.
Two structural reasons explain the skew. Adult traffic monetises on volume rather than on trust. An audience of strangers reached once still has value, which is not true for most categories, so an account with no history and no reputation can still be economically useful.
And the content does the persuading from the avatar alone. There is no need for a bio anyone believes, a posting history anyone reads, or engagement anyone notices. The account only has to exist and be seen.
These accounts are not badly built. They are built exactly as well as the job requires.
That is why they dominate the follow-bot population, and why the accounts following you look interchangeable. Circleboom's own analysis of the size of the NSFW community on X puts numbers to how large the standing population is.
What it is costing you, quietly
There is no penalty and no alert, which is why most accounts carry this for years without addressing it.
The cost is a measurement error.
Engagement rate divides interactions by follower count, so accounts that add to the count and never interact push the rate down without anything about your content changing. An account with 10,000 followers carrying 2,000 inauthentic ones reports a rate roughly 20 percent below what its real audience produces.
If you use that number to decide what to post, you are steering on a broken instrument.
It also shapes how your account reads to anyone evaluating it. Brand partners, sponsors and collaborators run follower-quality checks as a matter of routine, and a visible synthetic ratio reads as either bought growth or neglected maintenance.
Neither is what you want, and both are fixable in one filtered pass over your NSFW followers on X.

How to remove NSFW accounts following you on Twitter
The work is three phases, and the middle one is where the accuracy comes from.
Connect your account and pull the flagged list
- Log in to Circleboom Twitter and connect the X account receiving the follows.
- Open the Follower and Following menu, where the audience-quality views live.
- Select Fake/Bot Followers and let the full retrieval finish. Circleboom returns the accounts that cross the suspicion threshold across several signals at once, not just one.
Narrow the list until you trust every row
- Sort by Joined, descending. This puts the newest arrivals at the top and makes a recent wave visible as a cluster rather than as scattered rows.
- Open Filter Options and stack signals. Fake/Spam, plus Eggheads, plus a Tweet Count ceiling around five, plus a Join Date window covering the wave.
- Use Find in Bio and Name for whatever phrases the current wave repeats. Adult promotion accounts have to advertise in the bio, which makes text matching more precise than any behavioural score.
- Whitelist anyone you recognise. The protection persists across every Circleboom feature and every future session, so a known contact with a thin profile cannot be swept up by a later selection.
Remove the reviewed segment
- Select the confirmed rows and click Remove Follower, which stages them for the Remove Twitter/X Followers Chrome extension.
- Leave the browser open while the extension works the queue. When the API quota is reached, processing pauses for 1 to 20 minutes and resumes on its own.
The order matters because each step narrows what the next one can get wrong. Sorting shows you the shape, filtering cuts the scope, the whitelist protects what a signal model cannot recognise, and only then does anything irreversible happen.
Skipping the middle phase means running a bulk action on a list nobody read.
Quick recap: pull the list, sort by join date, stack four signals, whitelist, remove.
Why reporting them usually does nothing
Most people report these accounts for their content, and that report has nowhere to land.
X's Adult Content Policy permits consensually produced adult media as long as it is marked sensitive. An account posting marked content is compliant on that axis, however unwelcome the follow is.
The rule these accounts actually break is platform manipulation and spam, which covers mass registration, inauthentic identity and automated behaviour at scale. Report on that basis and the report is at least pointed at a real violation.
Report the account, not the content.
Even so, enforcement timing is not yours to control, and the accounts sit in your metrics until it happens.
Reporting is worth doing and it is not a plan.
How to tell a real follower from a network account
The single most common worry about this cleanup is removing somebody real, and it is a fair worry. Every individual signal catches ordinary people at the edges:
- No profile photo describes privacy-minded users and plenty of legitimate regional accounts.
- Zero tweets describes read-only users, who are the majority of accounts on the platform.
- A recent join date describes everybody who arrived this month.
- A lopsided follow ratio describes new users who followed 500 accounts on their first day.
What no real person matches is the intersection of all of them at once.
An account with no photo, no bio, four tweets across nine weeks, 3,200 outbound follows, eleven followers and no engagement history is not a shy human being. Circleboom's classification is built on that intersection rather than on any single threshold, which is why the result arrives as a candidate list you review rather than as a verdict you execute.
Expect roughly a quarter to a third of any raw flagged list to fall away under review. That attrition is not the scoring being wrong. It is the difference between a probability and a decision, and it is the reason the review phase exists at all.
Any one signal describes somebody you know. Four of them on the same row does not.
Should you remove them or block them?
Removal takes the account out of your follower count without preventing a new follow. For a dormant network account that has already moved on to the next visible handle, that is usually enough, and it costs nothing if the account turns out to be a real person with an unusual profile.
Blocking closes follow, visibility, replies and messages at once. It is the right level of force when the same cluster returns within days, or when the accounts are putting links into your replies rather than sitting idle.
The asymmetry decides it. A wrong removal reverses itself, because the person can simply follow again. A wrong block is permanent until you go find it, and there is no batch undo.
Because Circleboom runs both paths as an official X Enterprise Developer company, the pacing stays inside X's documented limits either way, with automatic pauses rather than pushing through.

Can you stop NSFW accounts from following you at all?
Not completely, and any guide promising otherwise is overselling.
Protecting your account works, because a protected account cannot be followed without approval. It also removes you from search, quote posts and open reach, which is a large price for a problem that a quarterly cleanup handles in under an hour.
The realistic controls are narrower:
- You can watch new arrivals as they land rather than discovering them months later, which is what checking new followers on Twitter is for.
- You can tighten your notification quality filter through X's own settings.
- You can run the cleanup on a schedule so the accumulation never gets large enough to matter.
What you cannot do is leave the target pool while remaining visible. Distribution is the input, and the two arrive together.
If the visibility of this content in your own feed is the part bothering you rather than the follows, that is a settings problem with its own answer, and how to enable NSFW content on Twitter covers the controls in both directions.
Summary
NSFW accounts follow you because visibility puts your handle in a scraped list, not because of anything you did.
They arrive in clusters roughly a day or two after distribution, they cost you engagement rate rather than anything more dramatic, and they respond to removal far better than to reporting.
Read the pattern once and it stops being unsettling. Run the cleanup within a week of any spike, while the join dates still cluster, and it stops being work.
For the wider taxonomy, why do random people follow me on Twitter covers the non-NSFW versions of the same behaviour.
Pull the flagged list first, before deciding anything. Once you can see the rows, the right action for your account is usually obvious, and you can clear the NSFW followers off your X account in the same session.

Frequently asked questions
Does having NSFW followers hurt my account standing?
No. X does not sanction accounts for who follows them, and you are not responsible for inbound follows. The damage is to your own metrics and to how your audience reads to anyone checking it.
Will they come back after I remove them?
Those specific accounts usually will not, because dormant network accounts move on. New ones will arrive the next time you get distribution, which is why this works better as a routine than as a one-time fix.
Why do I get them even though I have never posted anything adult?
Because the targeting has nothing to do with your content. The scrape collects visible handles, and visibility is the only criterion.
Is there any way to see how many I have without removing anything?
Yes. Running the Fake/Bot Followers view is read-only until you select something, so you can see the scale first and decide afterwards.
Do these accounts see my posts?
Yes, until you remove or block them. A follower has ordinary access to your timeline, which is a good reason not to leave the cleanup indefinitely if the content matters to you.
