Doubtful. I disappear for extended periods as a matter of course, so I suspect it would be a few weeks before suspicion that "this isn't just another hiatus" would begin to be significant. My parents know I am a member of this place, but they know no one on here's contact information, so I doubt notification would come easily. It would probably be dug up eventually (we have some sleuths on the forum that know enough about me to figure it out) but it would not be an instantaneous thing.
