As I said in a comment on the post asking about this community (and pinged the creator), I would give them the rest of Monday to get back to us about this community and their reasoning, and they never got back to me. Nor did they get back to anyone on that posted memes to that community, nor did they ever post anything in their two months here apart from creating that community.

Plus there's already a c/trotskyism community.

The account feels suspicious but obviously at this time we have nothing to go on and so will not ban OP.

As a general rule, be wary -- but not paranoid -- if someone DMs you for reasons that seem strange. Like if they ask a lot of questions from the get go or want to get to know you. Remember you don't have to answer anything you don't want to and you don't have to provide justification for it.
