Alright, let's contribute, just for the sake of...
I don't think the OP was being so innocent. He knew it was someone who got mad enough to drop over a little detail like the trap. Then he made not one but a few remarks mocking him/her over it. The reason why he targeted that player is quite probably because he/she knew it would get to him.
In the internet, those who care are the most likely to get trolled because trolls WANT their victims to rage. What's the point of messing with someone who doesn't give a darn?
That being said, I would have squelched the OP too. Even if I wasn't at the bad end of the "jokes", but just from seeing what he/she was doing to that other fellow.
Luckily, I haven't come across many trolls in DDO. I guess that in part because in game I am super chill, also because a lot of the players in DDO are adults. Not that adults cannot troll! But I do think that we cannot quite believe that what happens in the internet stays in the internet, hence there is some minimal level of decency.
So Cathimon, welcome to my squelch list!
