#6That bug ruined quite some archives and tainted all scanned legal documents before it as evidence. Its the sort of clusterfuck so big, its just burried by the omerta. Want out of a old contract? Ask for it to be presented.
Then ask "was it scanned and archived digitally" and if yes, claim that the document be invalidated on the basis of the scanning station altering the document.

> In 2013, workers at a German construction company noticed something odd about their Xerox photocopier: when they made a copy of the floor plan of a house, the copy differed from the original in a subtle but significant way. In the original floor plan, each of the house’s three rooms was accompanied by a rectangle specifying its area: the rooms were 14.13, 21.11, and 17.42 square metres, respectively. However, in the photocopy, all three rooms were labelled as being 14.13 square metres in size.
