Do you think Amazon gets raided? Do you know how many exit nodes are in AWS? My guess is lots because I know 2 people who have them and I don't know a lot of people.
It's also worth noting that there are a large set of tips and guidelines to follow for exit relay operators: https://trac.torproject.org/projects/tor/wiki//doc/TorExitGu...
... in someone else's data center.
Never, ever in your own home. If you are raided ALL your computers and ancillaries will be seized.
And the criticism of anecdotal evidence is that it may not be a representative sample. So what is the actual percentage of Tor exit node operators who have been incarcerated for it in the US then? Is it not 0%?
fbi will probably send one agent to pick up the server in the data center, and 20 others will be picking you up at your credit card billing address.
Did you hear of Lavabit?
Do you know they can force Amazon to handle access to all your running instances and you simple will never be informed?
