How the post removal checker works
Enter the subreddit without the r/ prefix, then your post title and body exactly as you posted them — links included, since a link is often the reason.
The checker gives the AI the subreddit's rules from the hand-checked catalog when the community is in it — promotion, links, karma and age minimums, flair, and self-promotion days — and otherwise asks the AI for the rules it knows. It never reads Reddit live.
You get each reason with the rule it comes from, and whether it is likely or only possible. If the rules cannot be read, the checker says so instead of guessing.
What the post removal checker tells you
- Reasons tied to real rules — every reason cites the rule behind it, so you can verify it yourself instead of taking the tool's word.
- Likely vs possible, kept apart — a link in a no-promotion community is likely; a missing flair or low karma is possible, because the pasted text cannot prove it.
- Hidden gates, surfaced — minimum karma, minimum account age, and self-promotion days are the removals new posters never see coming, and this check names them when they exist.
- Honest silence — when no rule the AI knows explains the removal, the checker says so, instead of inventing a reason that sends you fixing the wrong thing.
Once you know the likely reason, fix it before reposting — and check the next community first. Look up any subreddit's rules with the subreddit rules lookup, check your account with the Reddit account audit, and draft a rule-checked replacement with the Reddit post generator.
