So they "broke into Reddit" back in February and contacted Reddit in April. After Reddit didn't react they contacted them again a few days ago at this very opportunistic time.

They never specified exactly what kind of data they stole, nor did they prove it by providing samples.

For all we know this story could be entirely made up and they actually have nothing.

But even if they have something, them trying to come across as the good guys in this is so weird to me. No, you're not the good guys. You are criminals.
