Adsense arbitrage banned only to certain extent

Google Adsense have clearly mentioned that Adsense arbitrage is against their rules and terms and conditions, but GA does allow arbitrage to certain extent. You can do the later by combining Adsense ads with a service of your own. You may be getting your earning only from adsense and not from the sevice you are running, but google adsense does allow arbitrage, as it can not be mentioned as one. People can start their own arbitraging websites, provided that it does not clearly reveal that it a made for adsense site(MFA).
Make as much as you can, till the offer last. LOL!!!
