This fine gentleman is apparently chatbanned, but continues to join various rooms over and over (possibly in an automated fashion). His current name is intentionally offensive, as are his previous ones and it seems that despite being chatbanned, he can still join over and over and over, causing his name to be displayed prominently in the "descent from the top of the screen" animation.
In fact, he's even been copying chat transcripts about himself and pasting them as questions on sites that he isn't banned on. (weird, right?)
What recourse is there for a user like this?
