I made a bit of money in the early 2000s by writing Flash games and putting Google ads around them. Google eventually banned me citing a "no flash games" policy in their T&C, which (if it existed) was very selectively enforced. At the time I didn't fight it, just said "OK, I'll just switch providers, please close my account." Google did actually pay me the rest of the money in my account. But, since then, I've been disallowed from using AdSense on any new sites, Flash games or not, and, weirdly, been banned from Google Code too, so if I want to use a project on there I have to log out first. I've since stopped using Google services, even learned about postfix & dovecot so I could host my own email. Never looked back. Shame about the lack of viable alternatives to AdSense, though. I did use AdBrite for a while, though their ads were sleazy sometimes. Now they're gone.
