Email about locked CD account?

[Madison]

I just received an email from noreply@chiefdelphi.com that reads,

"Dear Madison,

Your account on Chief Delphi has been locked because someone has tried to log into the account with the wrong password more than 5 times. You will be able to attempt to log in again in another 15 minutes.

The person trying to log into your account had the following IP address: 46.118.157.232"

Has anyone else received similar?

I don't even know what my CD password is and though this says my account was locked, I'm able to write this from a browser on which I stay logged in.
