Really I feel like the thread mocked those sellers. A link to their auction was posted, they were ridiculed over their thought that they had something special (A Mac 128 made in 1983, for example) and then we warned against ever buying from them. I believe an educated buyer would be able to recognize a high price and avoid scams/ripoffs without being told.
As JDW pointed out, many of this forums members posted on that thread. Reading Scott Baret's and your post have both been somewhat enlightening. If you will indulge me a moment, when I first got my dog, it turns out he was barking all day when I was at work. The way I found out was one Saturday afternoon I got a phone call from my neighbor who apoplectic. He made horrible threats about what he would do if I did not silence my dog who had been barking incessantly for months. Well I was mortified, but my neighbor had done us both a disservice: first, by not mentioning it earlier, it made the job of training my dog much harder; second, he endured much annoyance and let it build up to a point where he could no longer even be civil about it.
I do believe as a community, we should endeavor to self-police the boards. Never once was that thread challenged by one of our established members. Perhaps if someone had spoken up, the tone of the thread might have taken a different direction.
As to your specific criticism, I remember that 1983 Mac. I remember the seller made claims that alluded to the fact it might be the only 1983 Mac left in the world. Again, much of the thread was to alert others to unsubstantiated hype. And that was a gross overstatement, designed only to mislead and build-hype and drive prices up. As far as warning anyone "against ever buying from them", I don't recall ever reading that written by anyone. Finally you yourself make our point for us:
I believe an educated buyer would be able to recognize a high price and avoid scams/ripoffs without being told.
You could not be more right. However, most buyers are NOT educated. Especially when it comes to eBay. We often see new Mac enthusiasts arrive at this forum only after buying their first Mac. By then it's too late, they've overpaid for their Mac and helped drive up the market. Buyer beware? You betcha', but where are they gonna get their information?
Lastly, I will point out that this forum regularly cuts Bill Gates and Microsoft NO slack. If anyone has never said a disparaging work against Microsoft on a public forum, please do feel free to stop by this thread and throw stones. Many say horrible slanderous things about Steve Jobs. Various tech companies are routinely raked across the coals in the most mocking and ridiculing of ways. I'm not sure how a seller on eBay, especially one in the "Super Seller" category in any way is exempt from the same criticisms, opinions and public dissection any other seller is. That said, some sellers actually benefitted from that thread. I recall a tirade launched against a $10,000 Lisa 1, which was more or less vindicated for actually being extremely rare thanks to the expertise of the members on this forum. Frankly, these sellers must be held accountable for their practices and they should explain themselves. While I don't necessarily agree with all of them, only one of the sellers whose name was mentioned actually explains his rationale behind charging some of his high prices. Could some of the opinions expressed in the now defunct thread have been handled more tactfully? Sure. But, the ability to post and criticize information about a public seller must not be denied. When the Soviets overthrew the government in Russia, one of the first things they did was shut down the newspapers and establish their own, so they could control the flow of information and perception of their actions. To remove the voice of the people to express their opinions about another's actions, especially a commercial vendor, is no different and leads to similar results.
Parting words: I just saw a 128K Mac on eBay listed for $950 with a crack in the case and two non-functioning 400K drives. The seller says it worked fine when he packed it away years ago as a selling point. Now how many of us so-called experts have discovered our perfectly working Macs packed away a few years ago now suddenly fail to boot? Am I really just supposed to ignore it and not offer my opinion? Clearly many others on this site are in agreement that such things are worthy of discussing, as much as finding some unique link posted for its novelty. Many of these links, such as an online System 7 emulator, are posted by our ranks and the creators of those sites are ridiculed and mocked by some members as well. Should we ban all criticism on this site? Should we only allow posts which offer praise and information only with no commentary? Then really what's the point?
