it's a realistic fear if you have someone in your life who has done something to make you think they want to track your data to use it against you... but how likely are they to know it's you and what do you have to lose? and THEY would be the ones in trouble for stalking you so everything the "had" on you would be useless to them.
just sayin.... (I am the SAME WAY as you... but my mother IS a stalker and out to get me or get something negative to use against me.)
