Some hosting providers are known for not caring about the activities of their customers, but in general, how would I know that the other tenants are scum?

I have access to a fairly large dataset of known bad hosting providers, but most people don't. So how do you tell the difference between getting a good deal and "this is cheap because it's sketchy as all hell".

We also don't block all of Vietnam, or all Jio customers in India, even if we know that 20% of bot traffic is from those two alone.
