Is it just me or does Gumtree.com who I think are owned by ebay violate the adsense rules in their classifieds listings. http://edinburgh.gumtree.com/edinburgh/free-classifieds_1980_1.html I'm no expert on adsense, but I thought you had to show the "ads by google" etc etc Look at the bottom of the page.
Naah, they are not violating the TOS. They've got those ads under the heading "Sponsored links", so people will know they're ads
