Not that I would condone illegal activity, but why not disconnect the Internet at the lawmakers' office buildings? Or, even better, after the 28th, setup a server in the office building hidden somewhere that's sharing a ridiculous amount of copyrighted material. And do it in such a way that the police will find out. Then the police have to choose between breaking a stupid law and disconnecting the people who passed i…
Once this law is in effect, you ought to be able to DoS the lawmakers by just (frivolously) claiming they were infringing copyright. If different people keep doing this (DDoS effectively) this could be kept up for a while. I suspect there's a danger of having to cover costs/damages if they investigate the case and it turns out there was never any infringement, but incorrectly claiming copyright infringement is hardly going to be a criminal offense.
