Sherlock Squawks says: look at his myspace.
www.myspace.com/soundofspeed Says 18 year old male. Look at the pictures. All of the same guy. Look at the car. Modified (slightly) - what kind of female modifies her car (extremely rare). Mentions Gary as his name numerous times. Got offended when someone said "Gary with the 'r' silent". Name is Gary. Case closed.
EDIT: In an addendum, I'd like to mention that it's possible his g/f, potentially named Karen, uses his account to post random, incomprehensible posts.
