Ezekial, Thank you for initiating a discussion which has evoked so many valuable responses. I think this shows there are still many who value Audiogon as a refuge from the outside world, which can be even more traumatic.
The most important thing is for the congenial majority not to remain silent in the face of unfair, or downright obnoxious, postings. Simply posting something appropriate, and in a civil manner, acts as a counterbalance. Many of us have adopted this technique instinctively whenever harassment rears its ugly head. That's why when reading through discussion threads one can see comments on both sides on most issues.
By reviewing sales feedback, and any past discussion postings, it is possible to gain some insight into the person on the other end of an Audiogon transaction. Providing a place for safer buying and selling, at fair prices, is still the most unique Audiogon function, for many of us. If someone seems to be out of line then no one has to engage in transactions with such an individual.
