(1) I don't have to anything

(2) if someone is a dissident I'm willing to take significant risk on their behalf, but only after I've verified for myself that they are what they say they are.

I'm not entirely green in this respect, I've run a number of services that were borderline legal and have had numerous run-ins with the law because of this. I've decided for myself that the amount of abuse does not make it worth my while on the off chance that one day a dissident might make use of the service. Feel free to adjust your strategy according to what you believe is the right ratio, I've done this for myself already after building up a fair amount of experience with services that lent themselves a lot less to abuse than tor.
