Today I enter my digg profile and saw this ad (ads by google) Mario Smith Blog Enjoy reading articles on my site Also check out the ads ! tudsy.blogspot.com I think It is against TOS but google accept it...
You mean you actually saw those words in an 'Ads by Google' ad unit? If they were in the ad itself I suppose AdWords must have accepted it. If it's anywhere else on the page then it isn't allowed.
Just under header, Digg has Adsense ads.. I don't know whats the problem here? Oops.. Just noticed the check out my ads thing..
@twin: so this dude Mario Smith (a.k.a. tudsy) advertised his blog with those exact words using AdWords. The quick answer - it is not illegal for him to advertise this way. However, if he said those exact words on his blog then it'd violate the AdSense TOS. In this instance, he's using a loophole to his advantage.
