Thomas G. Tcimpidis, Sysop of the MOG-UR BBS, has his personal computer and data storage seized by the Los Angeles Police when Pacific Tel determines that a message on one of his boards contains a stolen Calling Card number. He at the time did not monitor or read all the notes in all the conferences, so he did not realise that some people were exchanging stolen long-distance telephone credit-card numbers on his BBS.
