Data protection act?
If you thought you might be on their lists, couldnt you request copies and corrections to be made to it as per the Data Protection act?
At least then you'd know if they had someone on you, and what that might be.
As theyre not a Government agency they'd have no 'secrecy' get out.
Copied from Wiki.. So it may or may not be 100% accurate, but I'd have thought that they could fall foul of sections 4 and 5 at least.
