I still sort of doubt many non-hams would even know about the ULS in the first place. My guess is Facebook, LinkedIn or Google are going to give up more about you than the FCC. Those $25 online database searches will find your last couple of addresses, phones #, SSN, employers, family, schools. In the grand scheme a current address is pretty tame.
