As you may have heard by now, on Monday, Tumblr announced that in just a couple weeks it will be banning porn from its platform as part of a change to its rules. Now, of course, Tumblr has every right to run its platform however it sees fit, but it does seem notable that it wasn't all that long ago that Tumblr openly defended the fact that Tumblr hosts a bunch of "Not Safe For Work" content, explaining that they supported free speech, and didn't want to be in the business of carefully determining whether or not something was "artful" photography or just porn.
