G should stop the numeric filters/penalties (-40, -50, minus-whatever-they-are) and rely on a fair and objective means of detecting link quality and use it to minimize/stop PageRank passage from questionable pages/domains.
That would be nice, but clearly Google believe that they are not able to do this successfully. If they did they could actually follow through on their original statement in an ethical and responsible manner: There is nothing a competitor can do to hurt your rankings. (i.e. posting loads of spammy links to your site).
Filters and penalties that deliberately suppress pages (especially domain level) create new opportunities for malicious take-down tactics.
I agree 100%. Google is actually enticing morally corrupt webmasters to carry out these types of attacks for two reasons:
1. They make it easy to hurt competitors by allowing simple link attacks to succeed.
2. The offer no possibility (or very limited possibility) for the webmasters that are attacked to defend themselves.
If Google allowed webmasters who have identified themselves as site owners to disassociate their websites from certain links then malicious link attacks would be drastically reduced.
