How to identify and remove MFA sites from my adsense account? I think that's the reason I'm getting way to $$ for my clicks.
Just type the url you see on your ads into the navigator, and decide wether the site is MFA or not, if it is, filter that advertiser.
In firefox you can right click on the link and go properties. Scoll along the info box and you can see the link the advert links to.

there a lot of online tools to preview ads, i use googlock.com it allows to preview sites and block them, automatically forms the list of blocked sites, and the main feature it saves a date of blocking. pretty useful!
