With so many sites down today to protest SOPA and PIPA, it’s safe to assume that many internet denizens will turn to other recreational sites to fill the void (I’m looking at you, redditors).

But don’t think that just because you’re browsing the porn tubes, that means you’re in a SOPA Blackout-free zone.

In fact, many popular streaming porn tube sites have joined in the SOPA protest, and their participation ranges from blacked out landing pages to censored logos.

PornHub has placed a “stop censorship” bar over their logo, reminding users that the site, like other tube sites, would struggle to exist under SOPA and PIPA:

In fact, other tube sites in the extremely popular PornHub network participating in the protest too. This includes Tube8 and SpankWire:

Xvideos and XNXX have gone to greater lengths in protest of the legislation. Upon visiting their sites, users are directed to a landing page that announces the blackout:

SOPA and PIPA are laws that would lead to a censored internet, in the name of copyright protection. You may not have heard about them yet as the big medias are hardly covering the subject because they are all in favor of SOPA. This new set of laws was about the pass silently (less internet = more TV). It would allow copyright holders to shut down any site with user generated content (even just a little as it could be seen facilitating infringements), without due process, and create an American internet blacklist.

You can then access the site, but with this warning message:

One of the most interesting SOPA protests comes from TBLOP, or The Big List Of Porn. TBLOP is exactly what it sounds like – a giant directory of some of the best tube sites, pic sites, blogs, aggregators, and porn torrents on the web. They have greyed out every site on their list that might not exist if SOPA and PIPA were to pass:

TBLOP NEEDS YOUR HELP TO STOP SOPA & PIPA! FREE PORN IS IN DANGER OF DISAPPEARING. This is because of two new bills being voted on in the USA, called SOPA and PIPA. If passed, these bills could block or ban most websites. See the list below? The faded sites may soon be gone forever.

It may seem like a trivial thing – to put up these SOPA notices on porn sites. But just think how many daily visitors these sites have. Any little reference could spark further research into the topic – and knowledge is power.

Of course, can you imagine the freakout if some of these porn sites would have shut down completely, not just participated in the protest with censor bars and landing pages? Since this was basically a warning shot, a “see what could happen” if you will, by all means, resume your previous activities.
