If a user visits yourmy profile with an account I am aware of and then he tries to impersonate me, I can trace him then. Usually people stalk profiles with their real accounts to check the style of posting and learn about the person and then create an alt to impersonate them.
my s/t editDoes this happen very often?
When I read a comment from a new user that piques my interest, I look at their profile to see their posting history, quite innocently.
To think I might then be included on a "stalkers" list and, should anything happen in the future, be on a shortlist of suspects, makes me uneasy.
Surely anyone contemplating "cloning" you would be sufficiently motivated to cover their tracks by the simple expedient of using a throwaway alt for research.
An emphatic 'no' from me. (Does that put me on a 'potential suspects' list?)
PS
I don't disagree about profiles being made unavailable to non signed in browsers, slighly contradictory though that may sound.
