Please take this as a "Get Well Soon" card from alt.video.dvd.
Like you, we too have been spammed mercilessly by the one calling himself (among other names) "Archimedes' Lever". This potty-mouthed moron presents himself as knowledgeable at the expert level in virtually any topic that arises in the group from BluRay to Yeast Infection, but he always, without fail, descends to foul language and name calling. He insists that he is superior to everyone else and that he works in the most advanced technological areas in existence. He usually exhibits a particular fascination with multiple forms of the word "retard" in his posting.
Lately we have succeeded in shutting him up by issuing a challenge to him to solve a new numeric puzzle that he has refused to accept. The puzzle was developed by a co-worker and, to the best of my knowledge (I Google it daily) has not hit the mainstream. Since he cannot work on it beforehand, he can only accept the challenge by working on it in real time as I will only reveal one step at a time. This seems to horrify him no end and he has done nothing more than attempt to ridicule the process. BTW - he does this in spite of the fact that I have admitted that I could not solve the riddle. I'm not bothered by that fact as many of these puzzles do require some out-of-the-box thinking, but our Archie is fiightened to death of potential "failure" in front of others and will not take the risk. Hence, we at alt.video.dvd look upon him as our very own Usenet piñata.
Here's hoping you can similarly rid yourself of the menace that is "Archimedes' Lever"..
