UK "default on" ISP censoring will include "web forums" by default

The other way it works is that the police ask for your encryption keys and throw you in jail under the Regulation of Investigatory Powers Act 2000, Part III if you refuse to hand them over. At least with this approach you know when they are reading your emails and trawling through your search history and cached images and no one hits you with a spanner, even if you do take a couple of tumbles down the stairs on your way back from the interview room.

I had a meeting with a client (fairly significant global consumer electronics company) who had an issue with a hacker who had been targetting them his entire "career", the issue was that he used a virtual machine to store everything that was configured to delete itself if he didn't login every 6 hours.

Hence, when the police kicked his door down and hauled him into custody all he had to do was to keep schtum for that period, then happily hand over his keys, as it were.

This had annoyed the client quite a lot.
