Re: The word is out - TOR is compromised!
Your traffic can be detected at exit nodes. My understanding is that TOR is good for looking up -say- contentious things; but using TOR for any service you have to log into is risky. Good for evading ISP filters and country blocks and other barriers; but any passwords are at risk unless there's also another layer of encryption or two. Especially plaintext ones *cough* El Reg *cough*
Quick in-and-out, non-repeating beaviour (like -say- looking up symptoms that you don't want your insurance company to associate to you); fine.
Persistant use and logins; some caution.
As a quick aside; despite film/music downloading being perfectly legal here, Vodafone have taken it upon themselves to block The Pirate Bay. So non-TOR queries take you to this page:
http://castor.vodafone.es/public/stoppages/stop.htmopt
...which calls this javascript
http://castor.vodafone.es/includes/jscUtils.js
...(some kind of fingerprinter?). Anyway, 5 seconds and TOR later, blocks like these are not a problem.
