Google Adsense Policy violation found in thread:category not defined in the....

Hi Tony,
Tpday I found a serious issue. In a forum message called Category not defined in the bookmark section I found 4 google ads. One in the top. Two next to the Post and fourth next to POST COMMENT. Is this not a policy violation of google? If it is happened by mistake I think it should soon be looked after as there is a chance of Google banning the user's account.

Please check the same.
