As I admitted in my earlier post, there really is nothing that can be done about this ultimately, and it is the fault of the person that made the mistake, leaving them at the mercy of the lowball-buyer.
However, when you plainly say not to judge or curse those who benefitted, I only generally agree. When I look at the spefic incident I brought up, I feel judging and cursing is more than appropriate. Those who were already judged by the community at large to be such nice people proved to be beyond reason even when given a chance to accept a mutually beneficial solution. Versus, you know, one that shit all over someone they knew just for their own opportunity to be as greedy a fuck as they could be.
As far as communicating what happened. Better late than never. The truth should have been spoken then, but I didn't want to make a big deal of it.
