What is preventing them from putting the site up? If they worry about the attacker logging into customer accounts (which, because they claim the passwords are salted & hashed with bcrypt seems not probable) they could just reset all users' passwords and let them log in using activation code. People that have 2nd auth via Google Authenticator will be even more secure this way*. Doing it like this would enable users to decide for themselves if they want to shut down their positions or not. Doing it on behalf of users against their will is just wrong to me.

*there's always a possibility that the attacker tampered with the database. But it's nearly impossible to tell which data was tampered with and which wasn't, so either way they're in pretty hot water.
