Logic should suggest that if you have 6.5 million posts on an ADULT GENRE forum it became popular for it's content and....genre. Ditch adsense and find a different method to monetize. Consider CPA..there are tons of Adult Dating sites that will pay you per free signup or upgraded membership. You can also get involved with JuicyAds.com or off Dating Manuals etc. Adsense wouldn't make sense on an adult site even if it was allowed.
NetStar is RIGHT!!! Why Use Adsense if They Don't Allow Adult Content??? You will hardly ever get a related add for that space only banned.. for life!! Use Banners from Adult Category sites that pay per click like SinglesLog or JucyAds like NetStar Said!!!
instead of clean up the forum, why dont you make a new forum the present adult forum can be used for adult affiliate program or/ adult PPC advertising
thx fellas. anything else besides dating affiliates that you can come up with? @life: yeah i tried creating a new one. but its hard to get people to join, since everyone goes to the old forum that gets much more traffic.
