So, for the third time I've had an email saying my account (that I thought was inactive) has been hacked and subsequently frozen for abusing the ingame chat.
Odds are, that those aren't real emails from Bliz. Most scam emails pretend to be official ones, but if you click on the "reset password" link (or whatever other one they give), they actually send you to some fake site like usbattle.netBlizzard-WorldOfWarcraft-Cataclysm.net/?=asdjkag...
...which really, really, isn't an official Blizzard website.
Especially if your account is inactive.
(I've even gotten completely official looking, with all the background graphics and everything, "Come back for a free week!" promotional offers.... but, again - the link they send you to is fake, to get you to type your password in for them.)
Phishing emails make me happy that Firefox lets me just mouse over a link and see what it actually is. Most of the fake ones, the actual link doesn't look anything like the one that's typed in the email.
