If you are an instance admin, you NEED to block instances, and do so EARLY when they are being run by people who are acting in bad faith
* Hiveway was very stoppable because they didn't have a critical mass of users for whom it would be seen as "unfair" to block them for their admins' bad behaviour
* Bofa was a lot harder to stop because there was like a million hand-wringing about how many users they had, and how it's "not their fault"
Block bad instances EARLY
