MANILA, Philippines – It’s not quite censorship, but blog service Tumblr has quietly changed its stance on Not Safe for Work (NSFW) and adult blogs, making it more difficult for people to find those blogs on Tumblr.

The Daily Dot reports that Tumblr has made subtle changes to its policies. These changes mean that NSFW and adult blogs cannot be found when using tags to search for content. Certain tags used to search for NSFW or adult content were also removed.

The changes also mean that links to blogs with NSFW or other forms of adult content have to be shared by people who know the link.

ZDNET adds that due to these changes, adult blogs are essentially cut off from both Tumblr’s internal search functions and most search engines.

The changes appear to go against existing Tumblr policies. On July 17, Tumblr CEO David Karp was on The Colbert Report, saying Tumblr had “taken a pretty hard line on freedom of speech, supporting our users’ creation, whatever that looks like, and that’s just not something we want to police.” – Rappler.com
