Indie developer and publisher Mojang has announced that it will join other websites tomorrow in protest of SOPA, the US government’s Stop Online Piracy Act. The Minecraft creator joins organisations including Wikipedia to disappear from the internet tomorrow as a stand against SOPA, an act which many view as ushering in internet censorship were it to come into force.

The Act in its current form would allow the US Justice Department and copyright holders to seek court orders by which they could block access to websites breaching copyright, alter search engine results, and bar advertisers and online payment facilitators (Paypal, for example) from doing business with potential copyright infringers.

While this may initially seem like a move to crack down on crimes such as movie and game privacy, the current scope of the Act could potentially allow action to be taken against anything from screenshots to video walkthroughs.

In protest of the proposed Act, Mojang will be taking down its website and those for Cobalt and Minecraft. This will not affect their game servers. Other such sites who are committed to such action on 18 Janyary include Wikipedia, Major League Gaming, Reddit and Boing Boing.

In a statement on the Mojang website, Notch said:

“No sane person can be for SOPA. I don’t know if we’re sane, but we are strongly, uncompromisingly against SOPA, and any similar laws. Sacrificing freedom of speech for the benefit of corporate profit is abominable and disgusting.”
