WoW Screenshots allegedly include Account names, IP info
...users on the OwnedCore forums did some digging and discovered watermarks within official (read: not taken by third-party programs, ala FRAPS) screenshots that, when decrypted, reveal three key pieces of information: 1) your account name, 2) a timestamp of when the screenshot was taken, and 3) the IP address of your current realm. (Note: that’s not your IP address.) Many users – among them, PC Gamer – then went on to verify that this is, in fact, true...Well one way to counter this they say is to set it to high quality screenies (which I THINK I have already I'm off to do it again just in case) by doing this:
/console SET screenshotQuality “10″
Of course, if I stopped being lazy and renamed all my screenshots that I uploaded... I wouldn't have this problem.
So what are you waiting for? Set it to high quality screenies NOW!
