How Your Username May Betray You
An anonymous reader writes "By creating a distinctive username—and reusing it on multiple websites—you may be giving online marketers and scammers a simple way to track you. Four researchers from the French National Institute of Computer Science (INRIA) studied over 10 million usernames—collected from public Google profiles, eBay accounts, and several other sources. They found that about half of the usernames used on one site could be linked to another online profile, potentially allowing marketers and scammers to build a more complex picture the users."
Seriously, that's almost precisely why I've the same username all over place (amusingly, almost except /.) - so that people who know me on one might recognise me on another.
I'd imagine that anyone with a desire to not let anyone know where else they go on the net already gets all their usernames out of pwgen or something.
Hey slashdot, why don't you be ahead of the curve on this and let posters change their username associated with their comments once every few years. Also, being able to delete an occasional comment would be thoughtful too. It's not 1995 anymore on both accounts.
And the installed fonts, and the screen resolution and color depth and the dozens of other factors that combined allow you to be tracked.
Try this web site for an idea of how these factors can (in combination) uniquely identify you:

I see that my browser is unique among the 1.4 million tested, with 20 bits of identifying information. Knowing my user name isn't going to compromise my privacy all that much more, especially compared to how Facebook screws your privacy every day.
Be at least 8 characters long. Have at least one upper and one lower case letter, a number, a symbol and an RGB code for your favorite color. Oh and change it every 6 months too.
Sorry about the mess.
Could we just move tautologies to idle? Or maybe we need a /. section called duh...
