......if you are going to call someone out in a public forum, and, btw, that is exactly what you are doing when you are a well-known chip dealer posting user names of customers you won't deal with on this board, you either a) back up why you won't deal with them with some concrete reasons or b) DON'T POST THE NAMES IN THE FIRST PLACE. You are free to choose who you want to deal with. Calling someone out in public is an entirely different matter altogether.

If it were me, I would be upset too, and doubly upset when the answer I get is "I am sure there is a good reason why I banned you, but I forgot why, so too bad."

Where I come from, that answer would never do.
