you don’t have anything to worry about. you can’t be tracked that way. are you just trying to find out if some one is on line? you should use buddy spy for that then.

why do you want your name off their list?
what sense does it make to remove your name off THEIR list? can’t you just block the person you don’t want contacting you and leave it at that? if you sign on at any point you’ll be invisible to them, and if they try and IM you, it won’t reach you coz you blocked them. or does it work differently for you?
