agree I think tor is such a cool technology but even the thought of what is getting routed through there on my machine or even a machine I rent is enough for me to stay away from it
I watched Adrian Crendshaw's DefCon talk about how people got busted using Tor and have also stayed away since then. I have used it in conjunction with TAILS a few times, but other than that, I don't mess with it any more.

You don't route anything by default, you have to explicitly enable it if you wish to help the network.
And relay operators (not exit nodes) don't face any issues. Don't let the unreasonable fear blind you.
Same thought for me with Freenet about 15 years ago.
I liked the idea of it, especially since it was a time where ISPs were really cracking down on BitTorrents. But after seeing a few index sites inside the network, I quickly realized how much of that network was CSAM.
Deleted that and never looked back.
