It looks like the chances of SOPA being shot down are slim. There is way too much money in the right pockets for much hope of stopping government censorship of the internet. At least this, coupled with NDAA, should be a clear enough example that the voting booth is a placebo button and that our government has gone off the rails.
If you don't know yet, SOPA is a bill that will allow blocking of any website accused with or without evidence of copyright infringement. This means censorship of any site not liked by big media and the government. There is no denying that censorship of alternative opinions is how this will be used. When it is used in this manner most people will have no way of knowing that something is missing from the web.
Fortunately, this is censorship on the DNS level. DNS servers will be required to block access to websites based on URL names but this wont do anything to stop people from accessing these websites by entering the IP address directly. The link below is a reddit page dedicated to displaying the IP addresses of common websites and the sites most likely to be censored first. In addition it has the goal of finding other means of circumventing this new censorship. You should visit, contribute if you can, and make a backup of what has been posted there.
It is nice to know that there will be ways to see the whole Internet after much of it has been censored, but it is important to remember that there are other reasons this law needs to be killed for good. If SOPA passes those of us who know the tricks will still be able to see what is out there, but the majority of people wont. The majority of people will see the internet handed to them by their government. Because censored sites will see less traffic powerful search tools like Google will become much less reliable. These are just a few of the reasons SOPA is a bad idea.
Call your reps and get the word out. If a person votes for SOPA it means one of two things: They were bribed or they are ignorant of modern times. Either way, such a person has absolutely no business making laws for the rest of us.
