Better 3 Strike Law:
My idea is to change the law so 3 bogus takedown notices from any group and that group can no longer issue takedown notices. 3 strikes is fair right? (ironically most these groups have lobbied the hell out of many countries political systems to implement 3 strike laws against infringers.)
Then google/youtube, and all sites that host content under the unsafe harbor, should honeypot the hell out of their services. Post tons of public domain videos and works under accounts controlled by them, and if they receive 3 bogus take down notices from any one party then they can simply ignore all future requests from those copyright trolls. Problem solved in the style of the people who have created the problem.
