Although the agencies cannot directly cancel the reservations booked from elsewhere, they can find those with 016- ticket numbers and easily cancel them by visiting united.com.
Speaking of leaked personal information... the new flights that United booked for us still have the original PNR. Granted if my original flight was canceled because somebody wanted our seats on Air China, my reservation won't interest them... but I find it a little odd that United would respond to my claims of a fraudulent cancellation with another reservation protected by the very same information that was leaked in the first place.
