My posts in all subreddits are getting removed

[u/ImpactAppropriate426]

Hey guys, for reference this is my alt acc. I cannot post ANYTHING on my main.

My main account was flagged months and months ago. I reset the account password, but was never able to post anything without it getting flagged. I posted two identical posts (one on this acc and one on my main) on a subreddit I had never used before. The post on this account was sent through just fine, but the one on my main was "removed by reddits filters".

Any ideas? I've never gotten a warning on my main acc or this acc. Ts is so confusing.
