Maybe also an indicator in
Tor browser, showing the censorship level of the exit that they're using.
Good idea, as previously said, different counties block/censor different things, so simply changing a circuit will get around this (for now).
With reference to torrents in the UK, as Sam said, not all are blocked. Its basically a game of whack-a-mole with the courts. Every time the courts order ISP's to block a particular domain name (eg
torrent.com) the site will simply change domain name (eg to
different-torrent-name.com) until the courts order the ISP's to block it again a few months time. I am uncertain if, for example, someone were to set up a new ISP they would have to follow the previous court blocking orders or they would need to be "re-issued" to the new ISP.
Thanks
