Tumblr denies hack as pornographic images and vacuum cleaners plague feeds

Tumblr is experiencing technical difficulties, leaving some users confused by unwanted posts and images cropping on their accounts this week.

TechRadar first spotted the issue, reporting that unwanted posts included everything from pornographic pictures to random message — even a picture of a vacuum cleaner.

The popular blogging service has confirmed that the issue was not a hack.

"Earlier this morning, an infrastructure failure lasting roughly 15 minutes led posts created in this window to become corrupt," the spokeswoman said. "No data was lost, but this has been causing inconsistent behavior for these affected blogs. Our engineering team is working quickly to correct the situation."

There is no word on when the situation is expected to be fixed.

Tumblr addressed the glitch in a tweet from the official Tumblr account, informing followers, "Our engineering team is working quickly to repair an issue causing incorrect posts to appear on a small number of affected blogs."

Initial reports pointed to a Tumblr hack, based on the fact that a number of users were unable to log into their accounts to access their dashboards and delete the unintended (and often NSFW) content, according to TechRadar.

No matter the cause, many users spoke out about their unhappiness, including Twitterer @pinkmanesque, whose response to Tumblr's tweet was a simple "yeah thank you after 12 hours."

Some even circulated an "I survived the Tumblr hack of 2013" image (above), which may have been more appropriate last month when the iOS mobile app was breached. The company quickly pushed out a security update for all users, urging people to reset their passwords.

The blogging service was purchased earlier this summer by Yahoo for $1.1 billion (£724 million); since the acquisition, Yahoo has remained fairly hands-off, allowing Tumblr to continue operating as a separate business.
