yep, and here's my completely circumstantial proof.
in HL's last account, he claimed to play basketball
He already knows where GD is, he knows all the moderators and he makes fun of them as well-- for all the people who remember that far back when "masterspartan" first joined the site, he had "comedy shows" starring the staff and in these shows, he basically tried (and failed) to make fun of the moderators and staff by continually saying "suck my balls"
he's overly against all types of behavior he deems to be "immoral" (he called the strippers in KoG's post "sluts" )
and he just plain posts like him. gratuitous use of devil smilies, the grade school grammar, etc.
oh yeah, this is my last post for today, so night all, i'm off to save gotham city.
