good points
I got this in a FRmail & got permission to post details as long as I don't name the Freeper (for the safety of the sender)...
There was a paleoconservative Freeper who was banned back in April for racism. He put together hundreds of posts by the victim, and actually not only stalked him through different threads, but he also tracked down the victim IRL by going through his history, came there in person and made threats to him. He's got the creepy feeling that this stalker is also stalking you (I presume because he is extremely angry at being banned).
When was the first troll post you got? If it coincides with his being banned, well...
