is there a list of bad sellers?

i recently won an auction where the car that arrived was not as advertised. cosmetically the car was pristine, mechanically it was a disaster of undisclosed problems.

the seller won’t reply to my emails or phone calls. bring a trailer won’t respond to my requests for information.

i would like to warn others about my experience but have no venue to do so. any way to get the info out there about terrible buyer experiences?
