I'm not sure what the process is there these days. I've been a member there for over a decade. Until recently my work was blocking the forums due to a malware issue they had over a year ago. I haven't posted much there since I got access back. You might try pming Advres. He used to work for TGR and used to be an admin on that forum. So he might be able to lead you in the right direction or fix your problem. The Suit was the other main guy, but I am pretty sure he is long gone.
The forums there have little to no moderation. Always have. Hence the junk show, but that is part of the appeal of the site.
If I stumble upon who is watching the site, I'll pass it along. You may also want to check your spam email folder. The response you are getting sounds an awful lot like what happens here when people don't click the activation email link.
