I've said it before...the best list is the one you make yourself. Why? Because: You are creating it from ads that are showing up on YOUR site. You only have 200 spots in the filter. If you go with a generic list, or one that someone has created for some other type of content area, you are wasting a lot of those slots by filling them with sites that will NEVER (or have such a small chance) of showing up on your site. Look at your ads, visit a few of them (use the preview tool or manually type in the URLS, don't click the ads) and see for yourself. After a while you'll be able to tell the low grade MFAA sites. Don't assume, also, that after 01 June you'll be able to empty your filter.
Now they have switched to New Domain because of some TradeMark and Brand Name issue for Google Product. http://www.adsblacklist.com/ Before they provide the free list of MFA sites but now... There are 3 types of account. A basic account is completely free of charge (see faq for details). A Premier account allows you to generate a full list of 200 sites and costs just £2.50 p/m. A Premier+ account allows you to control your Adsense account directly through ABL. If you opt for auto-updates, ABL will regularly update your Adsense filter for you, removing the need to copy & paste from one site to another. Premier+ accounts can cost as little as £4.99 per month, and we'll even throw in a free blog/wiki site for you to display detailed information about your business & sites. Hope this may help you to find some...
You should not filter at all - unless you have business or private reasons to do so. Filtering ads just because they pay little just means less competition for the ad-space. That will lead to less, not more, money for you. Personally I only use filtering for the reason that I don't think the advertiser is ethical.
