How hard can it be to go to gmail.com, make another email that does not contain any references to your name, use that one for either wow or for forums and set it to forward all to your main email address.

What I do is:

gmailaccount1 for forums i like/trust
gmailaccount2 for randomsites that require me to login
gmailaccount3 for msn
...
those are all forwarded (and emptied right away) to
gmailaccount4 which is like a collector,
gmail4 forwards to my main emailaddress

they all have crazy passwords that i dont have to remember since i never log them in
if they would hack one of the emailaddress, the tier system makes it such that the rest of my 'accounts/data' is not compromised
