I say good riddance. When he first came around, he made me laugh. Some of his posts were funny. After awhile, especially after he learned I worked for the police, he had a personal vendetta against me. I have put up with private messages from him, as well as constant e-mails. I put up with people like him at work and I hated dealing with people like him here in my downtime. When I ignored him, his e-mails to me increased as well as the personal messages. He got a kick out of asking me a question or making some asinine comment and then turning off his PM's so I could not respond.
Additionally, when my sister committed suicide, he saw an opportunity for personal attacks both in public and private (fortunately the mods removed whatever was public). I thought he was just pretending to be an asshole, but when he made comments about my sisters death, I realized he wasn't pretending.
He also couldn't stand that the police found out about his threats against the receptionist at his doctors office. He's made public and private threats to cut off her fingers because he blamed her for delaying his doctors appointment by 2 weeks.
While I thought he had a funny side to him at, AD is much better without him. With all the stuff he's done to me, not once did I complain to the mods here because I knew it would be a matter of time before he hung himself by his own deeds. That time has apparently come.
