I wonder, if you change your profile name ( I was thinking of that) does your profile not stay in "peoples" hotlist and they can always "check up" on you.

Yes it does if you look at the bottom of your profile there are 2 http links 1 with your aw name and one with an aw reference number the name can change but the aw reference does not so if they have you ref number they can go to your account no matter how many times you change your profile name the ref number stays the same I had this problem a while ago
