I think this site lacks troll techniques. Pretending to report and pretending not to be a troll are some examples of them. I think trolls here are too innocent. Underestimating is their biggest weakness.
And I don't think a troll ever becomes a permanent enemy of another troll. Because what a troll says is never serious, is just having fun.
There are more challenging forums than this site, that's for sure.
But who?
