not buying the friend list thing

The only thing that doesn't ring true is that it's "annoying" to clear your friends list.  Come on you take a few screenshots and hit 'x' a bunch of times.  Sure you have to add them back later, but you're playing a tournament.  Once people start messaging you during matches this should be obvious.

Also, the argument that he's "just 17" goes both ways.  He may be too immature to handle the backlash.  He may also be too immature to understand that cheating is a really bad idea.  I'd call that point a wash and it should just be left out of the discussion.
