Backstage, the casting website I used, pulled through. They responded swiftly, removing his ad and closing his account. They sent me a copy of the message they gave him, which basically said "we've gotten several complaints* about you being a dickface and also your contact info is sketchy so we're suspending you until you learn to play nice."

See, everyone? The Hollywood machine isn't as soulless as you'd think!

*actually they only got mine but they wanted to keep me anonymous and they figured he was probably being a jerk to others so they inflated the numbers.
