Would-be hackers often “ping” a lot of possible e-mail addresses to see if they can access an account. This is especially true if they acquired a functional e-mail address from a site that was previously hacked. So say you belonged to [insert website name here] and that site was hacked. The hackers would have access to a functional e-mail address, and they then might try to reset your GW2 password using that e-mail address.
Fortunately, the system stopped them, but if you’re concerned, or if you’d like to just get a new account name (perhaps setting up an e-mail account exclusively for Guild Wars 2?) do feel free to contact Support and we’ll help you accomplish that.
