to send coldplay/yellowcard/fallout boy etc... any band of that skill level a blackmail letter that says "Unless I receive a check for $10,000 dollars within 48 hours I'm going to tell everyone how bad your music is." Or something like that. lol

If anyone actually does it please make me a copy and a copy of anything you get back if you do get anything back.
Dear jfreyvogel,

Unless you send me $10,000 I will ban you permanently from this site. I will also have your IP banned so you can't access the site at all.
