User blog:Finchelfanno1/Need some advice

A guy has been vandalising the glee wiki for the past three days. He keeps on making new accounts, and we can't even ban his IP 'cause he makes it through tor. I seriously need some advice on how to deal with this guy. We the admins of the glee have done everything we can but he keeps on vandalising templates with pornographic pictures making new accounts. Please give some advice.
