Bob, it sounds to me like you need to round up the committee (if your voice has any pull with them at all) and suggest that if this is where Fast Eddie wants to go with TV Tropes, then it's best to leave him to his own devices. In short, they should leave TV Tropes as well and just build a whole new website, one without Fast Eddie and Google Ads.
Project Wonderful is a pretty good ad service and would probably do a better job catering to the demographic since they allow you to choose what ads you want on the site. Also, they don't mind NSFW content one bit. (To give you an idea just how much they don't mind, they happily place ads on webcomics like Curvy for other sites like Slipshine. Not providing the links because both sites are so NSFW that you don't even want family looking over your shoulder.)
