The thing is there wouldn't have been a need for anyone to confront him about his behaviors had the admins of itch just taken action to suspend his account the moment it was brought to light that he is 11.
Why they haven't yet is baffling. This isn't a case where they missed the boat as much as it is letting a fire burn out of control and not putting it out.
The behavior isn't consistent with just some troll online, but it is consistent with a kid who thinks he's the center of attention and the fact that he is openly admitting to ANYTHING about himself and his actions is troubling in of itself.
