Try AN.ON / JonDo as safer alternative (Score 1)

If you're worried about this kind of problem with TOR, I'd like to point you to JonDos, the "sister project" of TOR. It uses similar technology (Chaum's Mixes, multiple proxies with encrypted communication between them), but unlike TOR you know exactly which servers your connection uses, and who runs them. You still have to trust the exit node, but you know which server IS your exit node, and who to bust if its operator should spy on you. Disclaimer: It used to be a research project called AN.ON, with the client called JAP. Now run as a commercial company called JonDos, of which I am one of the main developers.
