yep, I'm large like that. I've been buying/selling on forums waaaaaay before these vBulletin forum boards, like 1996 or so. People come and go on these forums and one bad transaction can follow you FOREVER.
Case in point. A few years back I bought an Olins rear shock for a 2005 Honda CBR1000RR (I guess 6 years ago, lol). The guy fedex'ed me an OLINS sticker...lol... I had sent him $750.
I tracked that mothefucker down to "hollywood bike night" forum, posted up his real name, work address, email, phone #, bike he rode, shit like that. The thread got (literally) over 1500 replies, and his bike club (RR) kicked him out, the forum banned him, his parents found out (he was here on a scholarship from Japan) and they pulled him and shipped his dumb-ass back to Japan....... thats pretty extreme, but believe me, you can't get away with ******* people over.
