robo-call
n.— «As far as telemarketers go, ask them to remove you from their list, if they continue to call (or if its a robo-call) then (don’t know about availability in other states) start hitting *57 (call trace) which logs the number with the phone company as a harassing call.» —“Re: Question About CallerID” by Dean Ridgway Usenet: comp.society.privacy July 9, 1994.
