Tumblr has lost 30 percent of web traffic since December

Since Tumblr announced its porn ban in December, many users reacted by explaining that they mainly used the site for browsing not-safe-for-work content, and they threatened to leave the platform if the ban were enforced. Some users say enforcement of the ban has been spotty — one user wrote into The Verge to say that they’re still seeing porn on the platform — but even so, users have apparently left Tumblr in droves. On December 3rd, when Tumblr first told The Verge that it would ban porn by the 17th, CEO Jeff D’Onofrio said in a statement at the time that users had other options.
