@jpaul years ago a big PL telco, #Netia, had a major leak, which unfortunately also included my personal data (I used to be a customer).
They then published a page explaining that they were "hacked" and that "hackers" came into possession of personal data, and so on.
I e-mailed them, using my address that was leaked — in a domain containing word "hacker"! — and said that if they immediately change the wording to stop slandering hackers I will consider not suing the shit out of them.
They did.
