When someone first comes to this forum, they will likely notice two things:
1) There aren't actually that many trolls.
2) The trolls that are here are extremely obvious.
It's that second point that usually concerns them. However, I would argue that this dynamic only exists
because we don't ban people for trolling every once in a while. You see, on most forums, there appears to be a larger percentage of trolls, but they are dealt with often. I would argue that the percentage here is actually the same percentage as everywhere else. Because we don't easily ban trolls, they don't have a need to keep making new accounts. However, this is where our system excels: because the trolls don't have to keep making new accounts, they actually feel like they need to preserve their reputation. All of a sudden, getting banned here means something. Warnings go much further here than I've seen them go anywhere else. Now, because the trolls actually respect the moderation team, we can get them to post constructively most of the time unlike other places that just get rid of them. I believe that we're much stronger for it. Plus, we don't have to do as much work.
