Might be best to send a message to Jason (TheNext) and ask him to look into it to double check, but this website doesn't have any code that i know of for ads, apart from the one at the top that promotes gameguru's products and the news latter.
Are you sure you haven't accidentally added an advertising add-on for your browser, or gotten a virus or something?
Scrub that, this must be more recent, i have them at the bottom of the forum now too. Never seen them before. But to be honest the fact that i have never noticed them until you told me they were means that whoever added them did a good job of keeping them unobtrusive, they don't seem to effect anything i do and most of the time they're in the footer where i don't go anyway, so i'm happy for them to be there if it helps bring in some revenue to pay for the website.
