The problem is mostly that technically you cannot have
"block only moving ads", or
"auto cancel havigation when a target page has more than 50% adsense ads".
Instead of that, people get what they can techincally have, that is, "block all flash" takes care of moving ads, and "block all adsense" takes care of MFA pages (one just arrives at a nearly empty page).
So we need a new HTML tag or attribute like "moving ad", and a sort of a meta name="mfa" content="useless". This way ad blocking software can discriminate between quality and less quality ads.
