He's Morley's ghost from Christmas past. He posted on FR back in the antediluvian period (pre-Noah), but was bounced for threatening to sue anyone - including JR, FR's proprietor - who disagreed with him.
His FR nickname was Batjack because his office was said to be strewn with Batman posters, Batman paraphernalia, etc. He was a rare and fragrant blossom, and I doubt we'll see his equal again. But the last I'd heard of Batjack, was that he was about to loose his license to practice law in Florida.
loose=lose
He went under Jack Thompson, Batjack, and Jackpeace...I think those are all of his names he used here.
