How do you Monetize your Website?

Shortly after I started this site I opened up a Google AdSense account with the hopes of somehow regaining some of the money I put towards it. Over the past few years I've found AdSense to be a fantastic service and must say that I'm very happy with the results that I've had.

Unfortunately, today I received an e-mail stating that Google has recorded "invalid clicks and impressions" on my site. Because of Google's strict TOS and lack of a disclosure process I'm left wondering what exactly to do. I haven't been promoting this site heavily, I don't purchase any type of advertising for it, and I don't submit the site to any type of questionable services that might endanger my AdSense standing.

I've actually decided to remove all Google AdSense ads until I get a response from the AdSense team...

Because I don't want to put my account at risk I'm thinking about looking for other methods of monetizing the site. I already utilize the Amazon Associate program and Text Link Ads but am wondering if anyone has had any positive experiences with other "contextual" advertising systems.

I recently had a brief conversation with elise from It's Really Just Me about this and thought it'd be a good time to throw it out to anyone else who might be interested.
