How does reddit filters work?

Well, I've checked and there are probably reputation filters. Some comments are visible and some are deleted by the filters. Some subreddits keep my posts but delete comments, while others do the opposite

in case you receive a response from your comments but not from your posts you should start by checking the subreddit guidelines and filters.this may be because of the manual reviews carried out in some NSFW communities for their posts to be visible.

No one knows exactly how Reddit’s filtering system works. If they did, everyone could easily find ways to bypass its content moderation.
