I am by no means lumping this guy in with this statement below, but sort of a rant on the new sellers emerging on the "newer" platforms.
This has been something that has come on fast in the past year. Mostly on the social media platforms, we have always had new folks enter buying then eventually selling and that is healthy. But there has been a glut of consigners with very little knowledge of the hobby. What pushed me away from interacting with the "big": name consigners on Instagram is a little of what went down here, no real indepth knowledge of the items they are selling, it is just a widget to them. The live sales are the best, you have a split screen with the consigner on top shouting at his clients and bidders all the rules. If they have something and you ask for a different picture or interior pics they come off as being annoyed. I have seen that especially when they host live events, when hot books are being presented they ignore questions regarding condition until they see someone claim it.
This is probably not the place for sellers to "figure it out" unless they are really willing to follow feedback.
