An apt description, to be sure. This troll is still at it this morning, though. Not sure who the lucky victims will be today...
From mhkking's post, sounds as if he's added a few to his list. Sorry to hear the jerk is back!
My son's forum is full of computer geek mods and admins. There's a way to trace back through the ISP and we've done it once there in order to file a formal complaint. Turns out our particular troll was posting from a college computer using a college's ISP provider. My son called and then wrote a formal protest letter (with a small threat of possible legal action) to the college. Somehow or another the college was able to determine which student it was and expelled him. I believe the student was on his own laptop but plugged into the college's ISP access.
Even though I'm one of the mod's on his board, I'm in no way a computer geek so I don't know all the in's and out's of how it all worked. It did take time to do and I know during the interim, they blocked that particular ISP's access to my son's board in order to stop the trolling until the college did something. On a smaller board like my son's, blocking the access was inconvenient for only a couple of other posters. It may not be possible on FR because it could be one of the bigger ISP's which would end up blocking too many legit posters.
Hopefully this particular troll will get tired and move on. Of course, we don't know what action may be going on behind the scene here at FR.
