Nah he can be a dick at times but he isn't stupid.
I like the guy, and I also think he has the contempt for Kao that would lead him to write such a PM as implied. Hell, I'd probably write the same kind of PM if some internet faux-tough-guy threatened to contact my ISP about some forum postings.
/disclaimer about this all being conjecture on my part.
A. it isn't Bhodisattava.
B. if said PM was objectionable enough, and on top of previous viloations of said ISP's terms of service that the individual had been warned of repeatedly, then its time to escalate things. If someone wants to be a repeat forum annoyance, they should at least learn how to either user a basic socks6 proxy, or post from the chicago public library system which apperently doesn't give a sh*t about such things (which is where the majority of godraiden posts came from). I have no problem contacting ISP's when required for the more objectionable spammers and the like. Never have. though its not done often. This was a special case.
