We had a troll forum go at us one time a few years back. They would coordinate attacks on other forums. I think the name was SexSexWorld or something along those lines. Anyway, we fortunately had a real bloodhound on our staff who located them planning out this attack. Since they had discussed us a month or two before our URL made it into one of the search engines. When they started showing up we were prepared for them but eventually I had my server manager build in a re-direct for anyone who came from their website's URL. I think it somehow stuck. Not sure how it worked but I ended up testing it out myself an had to dump my cookies to get past it, I believe.

The best thing anyone can do that has others trolling, flaming or just causing trouble is to make them waste their time. This has worked very well for us, though we have a lot of staff to help remove things quickly. Let the troll rant and then erase him. Nobody likes to spend time on things only to see them destroyed. Trolls & flamers only will stick around as long as they have a voice. Take it and they're going to get tired. If they are milking your bandwidth then this won't really work for you but there are other options such as blocking them - if you know their IP's add them to the IP banning table in admincp.

The down side to making everyone register is that the search engines won't be able to index your site and you need that if you want to grow.

Always trade-offs..
