DNA, go and talk to the guy, explain what he's doing wrong. If this was a new rider that was clueless on the bike, we'd all be giving advice and suggestions for him to improve - why is this case any different? He's clueless, that much is obvious, and yes, there's an entertainment factor, but the guy is digging his own grave (financial, at a minimum) and it can be avoided with a few easy words, so why hold back? No one was born a builder, just like no one was born a motorcycle rider. We all learn from someone, and we'd all be worse off without help from others. If he ignores the advice, so be it, but at least it was offered. We wouldn't intentionally watch a clueless rider ride into the ditch, would we?
