Note that the instance in question is H-ToC, which I've done on three characters. Dustfire is my raiding character and has several ICC 25 pieces. Whether someone likes her gear or not, there's nothing that would make her worth trolling out of a 5-man.
To set this up, I've stopped raiding and have been leveling enchanting. Since I don't have any reason to properly enchant my gear for now, I've been using unenchanted pieces of my own gear to level it (obviously, I'll replace the enchants later). Also, note that [Abyssal Rune] from regular ToC is a reasonable alternative when a shadow priest is over hit-capped, which I am (by a lot). I'm sure there could be some debate on that subject, but it doesn't really matter for this situation.

I put them on ignore and then reported them for cyber-bullying me out of a pug. It was annoying, but more than anything I don't like the thought of people getting away with that kind of behavior. They harassed me for no defensible reason, they should be reported for it.
