Understanding Self-Promotion Tolerance

Each subreddit has its own culture around self-promotion. Knowing the tolerance level before posting helps you avoid bans and build genuine credibility.

High Tolerance

These communities welcome product mentions and project sharing as long as you follow subreddit rules. You can include links to your product in posts and comments, but genuine value should still come first.

Medium Tolerance

Self-promotion is allowed in specific threads or under certain conditions (like designated weekly threads). Read the sidebar rules carefully. Build some post history before sharing your own products or content.

Low Tolerance

These subreddits strictly prohibit self-promotion. Focus on providing value through comments and educational posts. Build karma and credibility first. Mention your product only when directly asked for recommendations.
