I totally agree with Brian. This is a relatively small community, almost a good old boys club, and all I am seeing is the same members leaving mutually beneficial kudos to the same members. The kudos threads have nothing substantial in them.
Justified or not someone leaves a negative and it gets pulled ? I want to read about the bad incidents but I suspect most are afraid to leave them.
I'm guessing that a possible reason people will not leave any type of negative feedback or comments is that they don't want to burn bridges. They don't want to get blackballed from buying books (kinda like a CAL's list) from that particular seller OR quite possibly a domino effect from other sellers as well who may be tight with him/her. Not everyone can handle constructive criticism or opinion, and can be vindictive on the Boards, especially when they are popular and people may rally around them whether they are right or wrong.
