Cinica - muting someone does not close off the ability to track. The "exploit" means that anyone who opens an IM channel who had a recompiled viewer would be able, through opening that IM channel, to know your sim location and, it's believed (though not verified through testing) the coordinates on that sim.

So, muting and mapping are irrelevant to this. You can find anyone's location by opening an IM channel without saying anything (you OR them).

The sim location information has been tested in a recompiled viewer. Coordinate information has not been tested in a recompiled viewer however the code seems to allow that. (There were concerns with breaking the TOS so this wasn't done).

As far as filing an AR - well, I guess you'd have to have proof that someone was collecting location information. But how would you know?
