The discovery of the forbidden relationships often revealed much about the local communities, be it a factory or a village. Denunciations were common, although they were not always motivated by the fact that a foreign POW was seen with a local woman. Numerous denunciations resulted from outrage at indecent behavior, adultery, or excessive noise. Guards were perhaps the most frequent discoverers of forbidden relations (it was their duty to prevent them and to periodically search the prisoners' possessions), but a number of guards warned the couples or tacitly tolerated the relations.
