It is literally a platform's responsibility to make sure they are being used responsibly, as well?

Imagine a gun range that was well aware that their grounds were being used in nefarious ways. We'd shut it down. A hospital that just blindly gave out pain killers to anyone that asked. We'd shut it down.

Does this mean that a zero tolerance policy is what should be used to shut things down? I don't think so. We have some agency to control things, though.
