Hello, I'm seeking some feedback about banning trolls. We've got a user on the Car Talk board who has been causing all sorts of ruckus, and we've now banned him for community guideline violations for the second time. (I banned both IP addresses he has used for these inflammatory comments.) Problem is, he is re-registering and generating a new IP address for himself as soon as we ban him. Is there any other way to keep on top of the situation, or are we going to have to keep banning him as soon as he re-registers under a proxy or new IP? Thanks for any input.
