BC thats a good idea to make a list of scam buyers. Itll help you all avoid proven scammers and that in turn keeps your costs down which keeps the bud cost down which makes everyone but the scammers happy. And fuck the scammers trying to get something for nothing from someone who earned their shit.
Anything to keep dishonest folks from taking advantage of honest folk is a great idea in my book.
You would just need mod endorsement to keep it locked because a thread like that would be a magnet for the scammers to argue and complain if it was open for all to post in.
