Contrary to some rumours, deviantART will not be shutting down or "going black" tomorrow. Instead all deviants are encouraged to create and express their opinions in this blog post here!
If you're not sure what SOPA & PIPA are, then I highly recommend this short news article by the BBC.
Protect your freedom on the internet and educate yourself about these bills!
Also, since some people have complained about deviantART not blacking out, here's my take on it.
Sites like deviantART, Facebook and Twitter are global communities, SOPA and PIPA are an affront to the freedoms we enjoy. However, if we were to "black out" and deny access, we would be limiting the freedoms of our users. I believe that every single person here has the right to decide which side they wish to choose and deviantART has the responsibility to allow that right, no matter what our opinion may be.
