Someone typed it into a computer at some time in the past, and after information is in a computer, it remaining in a computer is a much safer bet than "And then it got deleted and we never spoke about it again." For example, suppose a marketing company has a computer system which organizes people by households. They call a household and ask for a particular member. She's recently deceased. They type a note on that household's record, with the intention that the next person accessing that record knows that they should under no circumstances ask for the daughter who recently passed away in tragic circumstances. Some years later, a software or process bug results in that record getting entered into a mail merge.
