Let's say I made a website that would host adult content. I know Google has a mechanism to ban phishing and spam sites, but this is a pretty harmless adult-oriented website. So, let's say I wanted to use Google Analytics for this site? Would that be okay? Certainly not AdSense, which is understandable-- I've looked at their policy. Also out is Google Checkout, as convenient as that may be, I know that payment for adult services can be tricky and I would have to use a specialty payment provider. I'm still uncertain about App Engine, but I think it would be less of a liability to start the move away from that. Thankfully, Google Search doesn't really block much adult material, to my knowledge. Any other caveats anyone else can think of?
