Doesn't necessarily mean you're safe. I have billions of database entries in my possession. So let's say, I get your username and search it up on the Bitcointalk database.

Username leads to your email.

I grep that email within all my entries, and any average person will have most likely signed up on another site that was hacked so I will usually find someone's password in a soft password encryption algorithm or in plaintext.

This is where not using your password more than once in the same place comes in handy.
