That brings me to another idea. There needs to be some report notification system where after they deal with whoever you reported it pops up upon your next sign it saying something like. "Moderator has reviewed your report." Doesn't have to be long, just has to let people know that they aren't being ignored.
@Draak, I think we're on the same page, we're probably thinking of the same troll group because they come on the same time each night. And I'm thinking we're thinking about at least one of the "Queen trolls" that's on during this time. Yes I agree with you, they need to be handled. :/ With them, I most def say don't fight fire with fire, you need to fight their fire with intelligence and professionalism.
