thip - the problem is, it tends to encourage the trolls if we keep their comments while new people are scared off from the site. We've had a few people leave because they were badly trolled. The trolls get a kick out of seeing their comments and all the responses to their comments. If we're told about the problem quickly - preferrably by IM instead of public threads, we can knock out the comments and the trolls don't accomplish anything but eventually banning. Trolls go away if they're ignored or deleted into obscurity. If we have to decide between "catering" to artists who want to share their knowledge and artwork or trolls who want to destroy, I know which way I'm going to go. Cheers!
