Need a New Forum Report Option: "Report for Trolling"

There are plenty of trolls on the forums that get to continue doing it because there is no repercussion. They sit just on the edge of breaking the rules so they can't be reported. They are pretty obvious, so stacking up Trolling reports from different people could flag them to get looked at by a moderator for bans. Please add this so they stay in GD or go away entirely.

Edit: I'd like to thank the troll who arrived specifically to prove the necessity of this. Thank you, you've been a huge help.
