I went to court to try to fight a ticket about a month ago, and had to go through a metal detector. Only thing that went off was my shoes, none of the piercings did although the guy said my lobes might make it go off (he didn't realize they were made out of stone).
It's called STRETCHING your piercings, not gauging or up - gauging them.
