Well if this ban is for real we know exactly what happened:

The Troll has always spammed CP and at the same time informed the host that there is Cp here.

The host who of course had to react and not bother to distinguish between CP and Loli art. Reacts accordingly and pronounces a complete minor ban.

Let's be honest. The host doesn't really care… Until someone points him to CP and he fears for his own reputation!
