If it is a donation, then that doesn't equate to special treatment. If you want to sell the right to be part of an exclusive FS section, then by all means do it. But then if I pay for that right to sell in the section then I should also have the right to speak my mind about a cue in said section. But that is something that should be happening anyway but too many people cried about somebody calling out the sellers overpriced items or whatever. Problem is that you have several sellers that list 10-20 things at a time seperately and bump them independently. The answer is consolidation or listing limits. Max number of threads at one time. Having 1-2 threads at one time is one thing. Or the other solution is have a private party section and a dealer section and keep them separate.
