Yeah, i had this happen all the time when i modded a small subreddit dedicated to a specific dog breed. People would get pissed when we removed a self-promoting link since they usually turned into someone hawking some pet food or toy. Then they would get pissed at us, so we would have to ban them. Or someone would start picking fights in the comments, and then get mad when we would give them a 30 day timeout. It was a sub dedicated to people sharing pictures and asking questions about their little dogs, but holy shit would people come out of the woodwork to be shitty.
