I agree - this kind of behaviour, while well meaning is really pretty insulting and doesn't show this forum off in a good light.
People are not going to listen to you when you do things like this, and most forums have an unwritten rule not to just join up to promote another forum. Fair enough, if you had done that on my forum I'd have removed the link but left the thread open so people could flame you.
Spam is not cool man, grab a banner code from the gfx forum and post a MySpace bulletin or something if you want to help promote us.
I made a myspace bulletin. I've posted on other forums that were not MMA related and I've talked to the admins of those site and got their approval.
