That means it is displaying the Ads on its site which is allowed. It doesn't necesarily mean its in the Coop (In other words there is no danger youtr site would be linking to it which is what would cause a problem) Im sure Shawn will double check it but theres nothing they can do about sites displaying the ads.
But since you didn't see it as a coop link, there is no problem. It is just a site with coop code con it sending links out but not asking for people to link to it, just a way to get weight. EDIT: lol, ysf1, you beat me to it
I'm back from vacation so I'm refreshed and typing fast. Of course someone was putting my name to bad rep to a few newbies while I was gone so I have to sort that out
