I did… Until the police knocked on my door. They said I was lucky because they decided to ask questions first, but they technically could have siezed every computer in my house without warning. I don’t think you’d ever get convicted for something obviously done over tor, but having your stuff taken while they investigate is really inconvenient.

People who accept the fact that they will have to explain to the non-technical police that they are not the ones who did something bad and they’re only the exit-node operators. And, of course, the three-letter agencies.

Not Sure Actually.

That probably depends on your vps provider (if using vps). Hosting exit node at home is clearly a bad idea.
