If I were RightHaven I would try to provoke people on 4chan to do this, so then you could sue all of the people doing mass, automated infringement.Wow, just looked these guys up - what a bunch of douches.
I bet Anon target them for a DDOS soon. Although personally, I think a better tactic would be a mass, automated infringement of the items they are suing people for.
This seems like such an easy industry to get into. Just buy rights to a bunch of content, put the content in places that people often copy/scrape from, and then sue the shit out of them.
