Just listened. I think the most disappointing thing to me is that there are people in klal yisroel who have no qualms with calling another person all sorts of nasty names to his face, in a very public forum. As long as there’s a chance that the guy is just a victim of a terrible scam (which IMHO seems to be the case here), treating him like that is just evil. However much money any guest lost, this guy just lost many times more..
Aside from being rachmanim, we’re also supposed to be a nation of bayshanim. That people have no busha to talk that way is saddening and disappointing.
(Yes, I know people lost money, but that’s still not how we should treat any person. A person’s true self comes out בכוסו ובכיסו ובכעסו.)
