I have a rather strange idea for a forum based web site. It would consist of almost 100% black hat suggestions and spam posts. I am normally 100000% white hat, so this is unknown turf for me. My question is would google allow their adsense ads to be placed on such a forum/site? I have never been into an adult site ( not that my idea is adult ! ) so I don't even know if Google allows those type of sites to place their ads. Would having a black hat /spam topic type web site harm my other sites that are 1000% white hat?
