Zersetzung - Wikipedia
Tactics employed under Zersetzung generally involved the disruption of the victim’s private or family life. This often included psychological attacks, such as breaking into homes and subtly manipulating the contents, in a form of gaslighting – moving furniture, altering the timing of an alarm, removing pictures from walls or replacing one variety of tea with another. Other practices included property damage, sabotage of cars, purposely incorrect medical treatment, smear campaigns including sending falsified compromising photos or documents to the victim’s family, denunciation, provocation, psychological warfare, psychological subversion, wiretapping, bugging, mysterious phone calls or unnecessary deliveries, even including sending a vibrator to a target’s wife.
Returning items from the trash to the home, releasing mice or poisonous snakes (especially those whose poison works on contact and need not be injected) in walls or basements and alluding to topics referenced in tapped phone conversations is also popular, as is filling both the salt and pepper shakers with ‘pepper’; (in a controlled or export economy, as in times of economic hardship generally, ersatz pepper is typically made of sawdust-type substitutes such as bark or for example ’winter pepper’; see especially ’witzpulver’ but also ’monk’s pepper’). Usually, victims had no idea that the Stasi were responsible and indeed, it is probable that they not always were. Many thought that they were losing their minds, and mental breakdowns and suicide could result. The 'dissolution’ is likely at least occasionally intended to carry the same connotation as in such uses as ’dissolution of marriage,’ 'breakdown of the traditional family unit,’ etc. It should perhaps be noted further that no one had a monopoly on monitoring communications, whether in East Germany or anywhere else.
Man East Germany was great, guys
