Why checking subreddit rules before posting actually matters
Every subreddit is moderated independently, and the rules vary enormously — what's a normal post in r/marketing might be an instant ban in r/webdev. Most posts that get removed aren't removed for bad intent; they're removed because the poster never checked the specific rules of that specific community before hitting submit.
Reddit exposes each subreddit's official rules through a public API, which is exactly what this tool reads — the same rules a moderator would show you if you asked, without needing to dig through a sidebar or a wiki page yourself.
The rules categories that come up again and again
- Self-promotion limits.Many subreddits cap how often you can mention your own product, or ban it outright unless you've been an active member first.
- Format requirements.Required post flair, title formats, or mandatory information (e.g. “must include your budget”) trip up more posts than outright bans do.
- Topic scope. Some communities are stricter than their name suggests about what counts as on-topic.
