I have no way of knowing because it's not like the mod who deletes it says it out loud, but my wild guess is that it's mostly newbies since, in most cases, whenever someone gets a job, they try to adhere to the rules word for word, barely leaving leniency like AI algorithms. One "banned" or "wrong" word or phrasing and it's scrapped tf out without any context attached to it cause let's be honest, sometimes we get heated or just don't really care and write things in not the best of ways possible, that's a fact.
Anyway... I'm hoping for a feature to at least review deleted comments or something cause it's dumb to be scolded without any reason given. It might be a good reason but if it is, I wanna know. Don't just chokeslam someone and call it a day. The confusion of that user would be bigger than the possible concussion they might get from the chokeslam.
