actually ACTA is not even remotely as sinister as SOPA/PIPA.
it's a treaty, not a law. and it's got some copyright infringement provisions in it, but it follows a due process of law, and is more a treaty between signing countries, to not obstruct the pursuit of copyright infringements. It could be abused, but we've had it since 2005 (it's not new), and so far it doesn't really look very sinister at all.
whereas SOPA/PIPA attempted to criminalize half the population of the planet, and hand the internet over to a handful of media corporations to do with as they please.
there is however a new bill I've heard about, which is titled something like "stop **09** pornography act" or something like that, which I hear has some very unrealistic provisions (like sopa/pipa), but I can't comment knowledgeably about it at this time.
