So I have a website with a fairly popular forum and I run advertising with adsense on all of the different sections. I keep a tight lockdown on nudity/porn so that I won't get kicked off adsense but that's actually starting to kill the site. Some members are moving to alternative websites where there's a looser attitude and posting up porn is allowed in many of the sections. My thought to keep members happy is to create a new forum that would be private so guests can't even see it and the also create a different skin for it with no advertising at all. That way I can keep the adsense off the forum with the porn part and since I don't give the google crawler any access other than guest, they should never even see it. Good idea, bad idea or horrible idea?
