The secret signs of the criminals - look at your house. the fence etc.

[Ulli]

There are criminals in Lower Saxony that use some kind of runes. In German they are called "Gaunerzinken". I think the word Gauner comes from Ganev = thieve. Zinken is explained here: https://de.wikipedia.org/wiki/Zinken_(Geheimzeichen)

The German police is warning because of this signs. If you see it next to your door, than it is very possible, that your house is scouted by criminals.

It took me months to learn. It is so complex. I had really to force myself. All this Youtubers who say that you can learn it in a few hours are either liars or super intelligent.

But now it is very helpfull. How fast everything goes.

Ulli, Being no expert on these things,
to answer your question to the best
of my knowledge, my guess is they
probably use a similar set of ‘codes’ or
“signs” wherever this type of method or
system is utilized but perhaps and
somehow not as overtly manifested.
