I love the idea of having an ad co-op on my site, but I have a quick question regarding the TOS. The site that I'd like to add this to is a traffic exchange that has banner advertising (members add their own banners) on the surfbar. I'd like to place the code for the co-op on other pages, but I thought it would be good to check before I did this because I don't want to break the TOS. I'm assuming that this rule is in place to prevent the co-op from ending up in "banner farm" type situations, but if anyone could clarify this for me I'd be grateful.
