another fishing bb I belong to had had a similar problem recently, we will live with commercial enterprises in the for sale board, partially because many of the members are importers and/or distributors etc. So the odd, "we are getting XXX in" etc is fine. What we all have objected to is a certain tour operator spamming the board and members privately consistently. I guess it is the same here. To add insult to injury he got stroppy and then started accusing the board of elitism. I think he got the message after 200 one word replies of "prat" by individual members.
