The content didn’t violate Lemmy terms of service or be of anything illegal, just the rules the mod posted.

If the mod has a short list of rules that say not to post X, and a user specifically posts X, what can I do really do about it? They may get some downvotes, but the posts stays up. The post gets reported, but the post still stays up. I check back a week later, and the post is still there.

I can’t build a community up, and if it’s clear the creators of that community and/or the current mods themselves have moved on or simply don’t care, then I will just move on.

I just stop reporting posts and simply leave the community if the posts stay up for several weeks.
