Questions

A restriction that hides your account or posts from people who do not follow you, without notifying you. X calls it visibility filtering. FSB tests the four common kinds: search ban, search suggestion ban, ghost ban and reply deboosting. Full explanation.

X does not use the word, but its own enforcement policy says it can limit the reach of posts and accounts instead of removing them ("freedom of speech, not freedom of reach"). Some of those limits are labelled on the post; many are not. The effects are observable from a logged-out view, which is what FSB measures.

Look at your account logged out. Your own logged-in view always shows your posts. The fastest way is a live check on FSB, which runs all four tests from a logged-out view. Manual method.

X does not publish durations. Most restrictions we see are temporary and lift within days to two weeks once the trigger stops. Repeating the trigger keeps them in place. More detail.

Find out which restriction you have, stop the behaviour that likely triggered it (automation, bursts of replies, repeated links or hashtags), complete and verify your profile, and re-check after 48–72 hours. Step-by-step plan.

Reports are one of the strongest negative signals in X's ranking, so a wave of reports can contribute to filtering. A single report from one person is unlikely to restrict a healthy account on its own.

No. Premium accounts get prioritized ranking in replies and search, and FSB regularly finds restrictions on verified accounts. It can make deboosting less likely, not impossible.

Then it is ranking, not a restriction: posting time, topic, format, links (which X ranks lower), or simply fewer people engaging. Read how the X algorithm ranks posts.

A marker on your account or media that puts a warning in front of your content for many viewers and can hide your posts from their search. It is often a setting you can turn off yourself. How to check and fix it.

Yes. Checks are free. Guests can browse profiles for 15 minutes a day; signing in with Discord or X removes that limit and adds a dashboard, favourites and alerts. The site shows small, closable ads to pay for servers.

Never. FSB checks public data from a logged-out view and needs no password and no X app permissions. If you choose to sign in with X, it uses X's own sign-in page and only asks to read your public profile.

Yes. Any public account can be checked by handle, profile link or numeric user ID. FSB only uses information anyone can see logged out.

Every live check sends requests to X, so FSB caps how many it runs per minute to stay reliable. When the cap is reached, recently checked accounts show their last confirmed result and new accounts can be checked a minute later.

100 means all four tests are clean. Each detected restriction takes 25 points off, and the sensitive-media flag takes off 10 (5 when restrictions are also present). It is a quick summary; the four individual results are what matter.

Accounts on the global board and in dashboards are re-checked automatically, more often while someone is viewing them. Each result is added to the account's history graph.

Time spent viewing profiles while signed out, about 15 minutes per day, reset at your local midnight. Guides, FAQ and other pages do not count.

Guest access is disabled over VPNs, proxies and data-centre networks because they are used to scrape the site. Signing in with Discord or X works from any network.

Yes. On a profile, open Share to download, copy or post the status card. The same image appears automatically when you post the profile link on X, Discord or Slack.

Yes, with the live status badge: a small SVG that always shows the latest result for your account.

Each test returns detected, clear or unknown. A new restriction is re-tested before it is shown, a failed request never overwrites a confirmed result, and hiding caused only by sensitive-content filters is not reported as a search ban. No external checker can see X's internal flags directly; FSB measures their visible effects.

From X's public web data seen logged out, cross-checked against open-source embed services such as FixTweet and vxTwitter. Official counts take priority over third-party copies.

Many checkers run one request and report whatever comes back, so a single error on X becomes a false shadowban. Others report sensitive-content filtering as a search ban. FSB separates those cases.

Yes, a free JSON API: visiuun.com/fsb/?api={username}, rate-limited per IP. See the API documentation.

For checked accounts: the public profile data and test results. For signed-in users: the account you signed in with and your preferences. Guest time limits use a device cookie and network information that expire within days. Details in the privacy policy.

The board lists public accounts that were checked. If you want yours removed, contact @visiuun on X from that account.
