I think it's a bad idea to blanket report anything you deem as a troll to the Tribunal as an AUP violation.
As an absolute minimum it simply adds that much more load to what will be the Tribunal.
Mark it as low quality, and then just do not engage. Don't feel the troll's ego and rep by adding comments and replies. Stop rewarding the Trolls, just downvote for low quality, let it submerge, and move on.
Let's remember that those are not just trolls. It's an individual, acting with a scheme, that is polluting conversations and approvals/bids of niches. Also, new users don't know about this and WILL give him attention.
@Vico Biscotti makes a good point, people are unwittingly engaging -they don't know that some of the comments, posts, bids, etc are coming from troll accounts. New users are at a disadvantage unless the word gets to them.
And after reading the AUP, even if the comments don't violate it, one person using multiple accounts to appear as several is impersonation - one reason to ban, at least.
