deleting all comments it doesn't agree with

I would absolutely report r/family law as a whole, if I could figure out how. Apparently, if a moderator doesn't agree with you, they can just delete your posts? Step mom asked a question and unless you agree with this step mom, the mods delete your posts, without warning, thus deleting all factual and opinions related to this poster's questions. If normal people are not allowed to share their honest experiences and opinions, but yet OP or mods are, something fishy is happening. My posts all were receiving multiple up votes within minutes of posting, yet were taken down. How do I report mods and entire subreddits?
