That rule was made because people would make crazy alt names to bait msmg users into making posts about their names, thus getting them attention by rage-baiting or weird-baiting.
It never was intended to mean we can't talk about someone just because they keep getting banned and making alts. By that logic, someone can easily avoid scrutiny by just intentionally getting themselves permabanned and then trying to evade the ban. This guy repeatedly comes on and harasses us constantly with nsfw selfies, and we can't talk about it? That's not what that rule was intended for.
