The Hall of Fame for banned trolls has to go to Fast Larry. He would be any moderator's nightmare. Fast Larry was all about insults, racist comments, stalking and revenge. His ego made The Donald seem humble and his scorn was far worse.
Larry was a billiards instructor who started off as a know-it-all on RSB and Billiards Digest. On AZ, he stalked people. Larry was so bad his name became unmentionable for years for fear of cyber reprisal. We would only refer to him as "the unmentionable one" or FL. I one received a PM from him, wanting to get together with me for pool on an LA visit. I am not usually like this, but I simply didn't respond.
While his non-venomous prose could be entertaining and clever, he was not a laughing matter. His story nearly ended when he was slugged at a tournament by a fellow member.
Eventually he passed away in horrible circumstances. It was a sad, sad era for RSB.
