Well..........since we're talking eBay and canoes......I feel compelled to add a comment or two.
I'm a 12-year + eBay member, both buyer and seller. I've followed it since the earliest days, when, if you browsed for "canoes" you'd be lucky to find 2 or 3 listed. Nowadays, it's hundreds, or more. eBay has changed over the years, not always for the best. Human nature hasn't. People on eBay range from the truly naive and/or innocent to outright scammers and fraud artists. In between, are some honest folk trying to buy/sell and providing reliable info or asking basic questions and expecting honest replies. Some others are more content to rely on 'caveat emptor' rules, and will try to get away with whatever they can. But, then, lots of buyers look for a 'steal' where they can use superior knowledge to buy on the cheap and grab a bargain from an ill-informed seller. Such is life.
When I see an obviously badly informed seller making outrageous statements about an object, I don't hesitate to politely offer more correct info. Does that make me nosy, or interfering? Perhaps, but I do it in total privacy, in a non-threatening manner, and providing independent sources where the seller can go to check things out. In the old days of eBay, that sort of thing was always welcomed. I have had only a few negative reactions. You can tell pretty quickly whether a seller is mistaken, but honest, by the reaction. Hostility usually is a sign of a mal-intentioned seller upset at being found out. Decent folks aren't afraid of admitting a mistake; crooks don't like it. Obvious scams and outright frauds should be reported to Police; eBay takes far too long and does too little. Been that route too many times.
I think we can be helpful without necessarily becoming 'policemen'. I believe the world is better for having WCHA as a resource for sound, accurate info. The goal is for WCHA to become known far and wide as the info center to turn to when in doubt. It is a fact that "canoes" are an area which has been under attack in recent years from professional crooks; witness the number of times photos of rare, antique items have been stolen and then the item is re-offered by scam sellers. Or the number of faked up "salesman's samples" (using cheap Chinese imports as a base), that have been 'antiqued' with a craquelure finish to look old, with phony early trade names added, etc. Some of these have been sold by on-line auction houses that should know better.
So, yes, I think it's great to ask questions, to try to determine who the honest, but naive, sellers are, and to expose the crooks and scammers for what they are. And to share the knowledge, not just amongst ourselves, but across the canoe-loving spectrum.
As for the guy with that "gorgeous old sailing canoe" that he still hasn't sold for $7500 after several months, I was curious enough to ask him (once he mentioned being willing to take an offer less than his 'opening bid price'), if I could come and inspect the canoe, or if he would post more than one photo. Still haven't heard back; maybe because I hinted that my offer would be a bit less than he seemed to feel it warranted. In this case, his 'non-reply' was answer enough. Sometimes no words at all tell you everything you need to know. I won't be wasting my time travelling, and he won't be making a sale to me at any price.
