Jen observes that Adsense have made a few changes of wording in their terms and conditions (mainly minor changes) and points out one that could be linked to an attempt to crackdown and penalize comment spammers. The wording that they’ve added is:
‘In addition, publishers may not bring unnatural attention to sites displaying ads through unsolicited mass emails or unwanted advertisements on third-party websites. These activities are strictly prohibited in order to avoid potential inflation of advertiser costs.’
‘unwanted advertisements on third-party websites’ – sounds like comment spam to me too. If it is comment spamming that they are talking about I’m right behind them. Of course the challenge is to go beyond changing a policy and enforcing it – time will tell if they have what it takes to tackle this on a larger scale than just the one off banning of publishers that we’re used to for breaches of policies.
