Account locked due to acc-selling suspicion; What to do

Good evening… *ahem*

Your account does appear to have been locked, but not manually by us as a result of suspected account trading or selling. It actually seems to have been locked by our automated security systems, which implies that either this occurred prior to you potentially filling out your information after receiving a malicious phishing or scam email or that the lock has occurred directly as a result of this.

Please make sure that you firstly check your PC, just in case any sites you visited happen to be carrying some dodgy software;

Then please make use of our online webform to contact our Account and Payment team to inform them that you were locked and that you’ve potentially inadvertently given away your details;

After this, while awaiting a response, you may want to start considering creating a new email address to associate with your Battle.net account – if your previous login details are now in the hands of these scammers then changing both your email address used to login and your password (once we’ve recovered your account for you) will double the increase in security you’d have from simply changing your password alone.

Also, you might want to take a look at the following sticky topic that provides information on recognising these pernicious mails, as well as what to do if you happen to receive one;

Best of luck for a speedy account recovery and resolution. :)
