Here's a proposed solution from left field. Perhaps the bleachers?
Ban all rants about vendors and collect hard data instead and come up with a vendor rating/score produced by the forum's members.
As an example, here's my data from all the vendors I have used for the build of my car over the last year. I had a positive experience with those vendors in green and a thumbs-up. I would do business with them again. Those with thumbs down and in red I had a negative experience with and probably would not do business with again.

Part of my motivation for posting this is to show what I suspect is the norm. I don't think my experience is unusual. There are a lot more
than
.
I suspect that when a particular vendor is truly going south the mods are aware of things. Stuff goes on behind the scenes and off-line so to speak.
So, take the he-said he-said emotion out and simply give members the opportunity to cast one vote for each vendor they use. Over time the cream will rise to the top. EOS.
Mods...good luck tabulating the data.
