Disappearing posts?

How do I know whether my posts are being deleted by a mod or if it's a glitch? I made a couple posts a few days ago and I noticed that one got deleted that was rather depressing but I didn't think broke the rules (it was in the need for extra support forum) and I assumed that it was deleted by a mod who either misunderstood what I was saying, or that I interpreted the rules wrong. But now I'm noticing some of my positive and completely inoffensive posts are gone too. One was literally a thank-you and a compliment on the trauma newsletter and I think my attempt at a daily checkin disappeared. :( Have I been shadowbanned or is this a glitch? I'm hoping it's a glitch because I'm feeling very othered right now. Thanks .
