Don’t really know if you where really serious STN about getting retribution
Call it karma or call it what you want.

Up until I was 35ish ( 1990 ) there is no way I or my circle of friends would get ripped off by anyone ( mostly were drug deals since we never saw escorts then ), same goes if we heard someone was physically abusive to his girlfriend ( some girl we know ). Karma made sure the person did not try it again. I am older now and can not do the things I used to do, but I am sure I could hire people to adjust someone. Just my opinion but thieves ( scam artists ) are the lowest form of life and unless they are shown the error of their way they will continue to rip people off.
