Unwanted Ads by Google

I have a blog that has Ads by Google showing up w/o the owner of the blog placing them there. The are unwanted Ads!

For example, this post:

http://bullseyebaby.wordpress.com/2010/05/24/looking-throught-the-pinhole/

has ads for photography-related items at the end of the post, before the comments begin.

Has anyone else dealt with this issue?
