People seem to keep complaining about the same sellers. You know what would be beneficial?
This does not apply to every seller, but does seem to reoccur regarding the same ones. If we had names of sellers who can be proven to have done the wrong thing, a tally on a sticky post could be maintained.
For instance, I have bought a many blades online and the sellers description can be quoted as being perfectly straight or has no edge damage. When the item arrives, it is a mess and photos have hidden the problems.
If I can post cut and dry evidence stating that a seller said a sword was dead straight and it is bent like a banana, they should get a black mark for wasting my time and money.
If a seller constantly runs auctions then refuses to sell the item because it didn't go high enough, then this is reflected in the tally, which can save people staying up late at night to bid on poor sellers. If people can prove that it obviously occurred, they should get a mark against their name.
That way people can see who to stay away from. Many of these sellers have zero ethics and do more harm to the hobby than good.
If its a one off, then the numbers will show that. If nothing happens for six months of a year, it could be cleared. The latest mark could have a date attached.
This would NOT apply to things like shipping taking too long or they said it was shiner than it actually is or the signature was fake ,but would be chalked up at the discretion a Moderator. This should only apply to specific things and not be subjective. The blade either has rust or doesn't, it is either straight or bent, it either has a perfect edge or has edge damage to some degree
People keep saying read feedback or ask around for opinions, but that is rubbish. Negative feedback is easily and readily removed from auction sites these days to promote more sales. To get negative feedback removed by eBay is very easy. Also asking random people around the world what they think of someones business ethics is hardly a reliable gauge of what they are like overall.
Just some ideas, better than the current system of trial and error, with many people bagging out online auction systems as a whole due to the behaviour of a few.
