Today I got this e-mail. They put e-mail addresses and date of births of there users on there website

What You Can Do
You shouldn’t need to do anything - the data is no longer being leaked and no passwords were leaked so you do not need to change your password.
Really? The data is
no longer leaked? That is what you are telling your customers? No sorry? No excuse that you gave away the personal data and that it will stay forever on the internet?
I like #
MusicBrainz but this is silly and dosn't reflect the seriousness of what happened.
Luckily for accounts like this I use special crafted e-mail addresses. And I don't give away any personal data like birthdays.
