I find it highly ironic that you are making this statement today. Today, where it came out that the IRS leaked confidential infos on one political group to their political enemies [1].
I have no idea how you can make such a statement. Is it just naivety or what are your intentions? If information "is there" it is going to be used. No matter how sophisticated the flagging system is, the data is not stored in some secret vault only accessible to the great inquisitor.
The recent IRS events clearly demonstrate that government institutions are absolutely unafraid to abuse available data for intimidation if necessary. These are no just a rogue employee stalking his ex, but actions on a targeted, ideological level. The only data that can not be abused is the data that does not exist.
