I agree with encryp, even changing password or just having a different password for each site doesnt help as much. I always use a different password for everything but I happen to use the same email for AL and a social media site. And few days ago my account got banned as someone tried to hack into it. Thankfully tho the support team sorted it out and got it unbanned in no time for which I'm really grateful for.

Ps. Shoutout the the STS support for being awesome in times like these
