Google is known to be pretty strict with making sure that all Adsense publishers remain conformant to their policies. I’m not very old in this game but had read and heard enough (about google shutting down Adsense accounts without even warning) that I made sure to read their terms and conditions thoroughly. What got my attention was the very last line in the policy:
Hi,
