Never heard that one, though I could definitely see that happening.
As far as I'm aware, someone looked at the IP address of the account from which the posts were being made and traced it back to a computer terminal located within DMCH's Humble, TX, headquarters.
Though, I admittedly didn't actually follow these events myself as they occurred, nor did I confirm the IP trace - my info comes solely from hearsay, thus it may be correct, or it could all be a steaming pile of crapola generated by the great internet rumor mill.
