Sad, but... From my observations, Tor is defeated in Europe.
I'm covertly censored on one newspaper's blog. First noticed as some keywords combined with my name triggered an automatic censorship that raised a false "error 503" (further experiments showed that my messages passed through without my name, or by reformulating the contents, while my name and the keywords repeatably trigger the so-called error 503, even by retrying seconds apart).
For some time I could continue posting by using other names.
Then my IP address was censored, but I could go on by hiding my IP address using Tor. Just like in any other dictatorship, you know.
Since Bernard Cazeneuve's visit to De Maizière and the subsequent European agreement (to combat terrorism of course), even Tor doesn't get through.
From my observations, it could be that the European governmental agencies have identified nearly all the nodes of the Tor network. Keep also in mind that the Tor team now advises not to use it.
