I'm not sure that IT said he necessarily intends to stalk her physically (track could also mean 'track down on the internet'). Is it also a bad thing to just look up this information by some means? Personally, for me the answer turned out to be yes, it was not a good idea....but I don't think that its illegal or dangerous or that one shouldn't do it, as a rule. But its worth thinking about its effect on therapy and one's relationship with the therapist as growlycat pointed out.
