A while ago in sections such as Alt. Anime there would be certain members whom would act completely against the rules, acting almost like trolls, and would get away with it. Whereas I have previously been banned for minor offences such as signature offences. I have noticed it has decreased lately, but it was there.
I wouldn't want to name names, as that would either disgrace their name if they have changed, or give them unneeded attention if they hadn't.
