I didn’t look at the other thread until it closed. There is one thing that should be taken into account when you see a large number of ‘Shtick’ coming from one neighborhood: The word of mouth factor is much stronger than anywhere else. If one person in Boro Park hears about an opportunity, it doesn’t take long till everyone hears of it. Therefore, those who are predisposed to take advantage of certain offers have a lot of opportunities to do so.
This is besides the famous Morah Heter that you are not robbing a ‘person’, and not ‘really robbing’. The fact is that these people would never shoplift.
