Snoopy: plus they can sign off & be in guest mode and see what a person is doing... again, unless cloak. Adding someone to their enemy list does not really stop a person from seeing what you are doing, if that is indeed what you are trying to do.

I had to put myself in cloak at one time when some idiot was watching me and keeping track of what I was doing - what boards I was visiting, etc... it was really annoying. I finally stopped caring and took myself off of cloak. But cloak is the only real reason to "hide" what you are doing.
