A lot of mods thought they had a power downvote - the way reddit works where it hides your removed comment from everyone but you with zero notification (like a per-comment shadowban) is pretty annoying. I’d post in some subs and check with one of the comment deletion tools, and sure enough, that would explain why I’d get no replies or votes. Sure is annoying to take the time to express yourself and talk top people, and some twat of a mod arbitrarily or mendaciously decides your comment is not allowed and removes it.
