If you've spent a lot of time in Azeroth -- and chances are pretty good that you have -- you've likely snapped a screenshot or two chronicling your exploits. And you've probably posted those screens somewhere on the web, too.
What you might not know, however, is that along with those pretty pictures comes a batch of your user data.
First uncovered by a user at Ownedcore, it appears that Blizzard has been secretly watermarking any in-game screenshot taken by players of the massively-multiplayer game. The encrypted data includes user ID, a timestamp and the IP address of the server, though more sensitive info like passwords and other private data is thankfully absent.
Those customers certainly have a right to feel a little concerned about how their information is being protected. Just last month, Blizzard's Battle.net service suffered a major security breach, prompting millions of gamers to change their passwords and closely monitor their bank accounts for suspicious activity.
Blizzard has yet to comment on the screenshot controversy.
