It appears as if Wikia is not participating in the of SOPA by blocking out their site for one day. Wikipedia is.

Stop Online Piracy Act (Sopa) and Protect Intellectual Property Act (Pipa) are two bills being debated by Congress which many feel will curtail freedom of speech on the internet.

Even though wikia is not participating, would The Walking Dead and other wikia sites you edit like to join protest? If so how?

According to my post about this on Wikia help, the Call of Duty Wiki is participating.
