Yes indeedy! No more "Fishing Hurts" Google ads on my sites!

Here's the Google FAQ answer to help with Filtering your Google AdSense ads.

All you have to do is:
1) login to your Google Adsense account
2) select the AdSense Setup tab
3) then under that tab in the header, you will see a link for "Competitive Ad Filter". Click that link
4) enter in the text box, the destination URL for any sites that you do not want listed in your google ads.
5) Click the "Save Changes" button

This can also be used to block your competitors from advertising on your website. For instance, if you sell Fishing Hooks and you don't want google to show ads from websites that also sell fishing hooks, then you could add cabelas.com or basspro.com to your competitive filter to ensure that ads pointing to their website (and possibly stealing customers from you) will not be shown.

Hope this helps!
