Which one of those would I fall into? My DOB certainly wasn't fake on registration (I don't know how that would lead to an account being compromised anyway, even if it's fake it's still essentially a random number) and I assure you I haven't logged into any even remotely suspicious websites that use the same login I used for Origin.
The fact that there are so many cases that have popped up within the space of a few days indicates that there's something inherently wrong with EA's security surrounding accounts, not the users.
But hey, feel free to blame the end-user on this. I'm sure they all *adore* hearing how stupid they are right after they lost access to potentially hundreds of dollars worth of games.
