Don't worry; they're already fucked. Here's an incomplete list of things the hacker did:
Lost money on their Crypto scam they tried to push on this site;
Got charged $300K for the site's upkeep;
Made an enemy of the Furry fandom (a group of people who make up a majority of IT and cybersecurity) and the entirety of Kiwifarms userbase (a site populated by people who could charitably be called "ethically disinclined")
So... yeah I think our hacker is fucked 6 ways from Sunday.
