Yik Yak announced today that it will now allow users to post photos to the anonymous messaging app -- just so long as they don't include human faces. That means you'll be able to share photos of your dog, your meal and non-reproductive body parts, just not your face. Seriously, don't even try. The company will be actively monitoring photo posts (before they go live) in an effort to maintain content control. Users, however, will still be allowed to show pictures of themselves as part of photo collections in the Explore section of Peek. Additionally, the company rolled out phone verification in an effort to combat spam and make the app a bit more secure.
