On Friday, PCMagreported several claims of outdated posts being re-shared on users' timelines without their permission.

Earlier this morning, Facebook user Drew Calhoun reached out to the site through a Facebook Help Community post, inquiring about four photos that had been re-posted to his timeline without his permission.

Some users experiencing the glitch tweeted concerns that their profiles had been hacked.

A Facebook spokesperson told Mashable that they are aware of the issue "and are investigating." The company did not provide any further information about how the photos were resurfacing.

It's been a rough year for the social network, between accusations of heavily contributing to the spread of fake news and that time it "killed" a bunch of its users... Let's hope it can get its act together in 2017.
