http://www.adsblacklist.com/index.php I found this site today. I feel it interesting and very useful so I thought I should share it with DP members. Its free in beta testing. I hope my adsense revenue will increase after filtering suggested sites at AdsBlackList. Please share your experience with this site.
That kind of general lists are not very useful. Try to make your own list from the MFA sites most clicked on your site (with some script to track your clicks). Of course you'll need to mantain your list (at least every month) because each day appears many new MFA sites.
Apparently Google are dealing with the problem themselves now terminating all Arbitrage and MFA accounts.
