Which Advertiser Types Do You Put in Your Google AdSense Filter?

A WebmasterWorld thread has discussion on what type of advertiser would you automatically add to your AdSense competitive filter list. I.e. which type ads do you not want showing up on your site?

Here are some of the responses:

• Adult Related Sites
• Ringtone Sites
• Win Free Stuff Sites
• Irrelevant Sites
• MFAs
• Deceptive Sites
• Parked Domains
• Work From Home
• Etc.

I would create a poll here, but the answers can be so open ended. Which type of ads would you block immediately?
