Legality of naming people who owe money?

[Likalotapus]

I once lived in a small town that had one independent furniture and hardware store. Much of the business was done on credit with no credit checks, only hand written agreements. The owner of the store ran a full page ad in the weekly newspaper expressing his "Special Thanks" to a list of customers. There was a list of names published below. Everyone in town knew that that list was people who were behind on their payment without the ad expressing such. Maybe you should try that approach, it worked well for him.
