Very possible. Tangentially related, but deleted my account a while ago, went back to ask a question on a niche subreddit with a fresh account, and had my post shadow-deleted for lack of karma or whatever nonsense. Site is still riddled with bots despite all the high barriers to new users though.

It’s very understandable having to use Reddit for some niche communities, but don’t put yourself through it if you’re getting banned just for having a different opinion.
