1. How is the scammer tag not appropriate for businesses?
Just my opinion. I don't think the forum should be the judge, jury, and executioner in situations where we don't have access to all the information. Courts work because they can order records and compel information, we can't/won't. Scammer tag was never intended for these types of situations, and trying to make the square peg fit in a round hole will probably do more damage than it will solve.
2. "Shouldn't be judged by one action". Well BFL has approximately 20k+ preorders and that is being quite conservative. Should I assume that taking PREORDERS for 11+ months by many thousands of customers as ONE ACTION? Come on that shouldn't even be used in the same page of text when writing about BFL. ONE ACTION? Hardly...
I don't care about preorders. If they were denying refunds as well, or making zero progress (they have made some) that would be a different story, but they aren't. People are more than capable of getting their money back any time they please. And yes I know it's dollar denominated, every business does that, even outside the "bitcoin world". Kinda seems hypocritical to ask for a scammer tag, while at the same time willingly allowing them to hold onto your money (yes I know you don't have an order with them, I mean in general).
Let me quote the topic for you
Scammer: Inaba
Why do you trying to shift this to something about BFL? To get Inaba out of the line? He personally (and not BFL) made a bet and it is crystal clear that he has no intention to pay despite losing it. So please stop trying to derail this by bringing BFL into the mix.
And BTW, since when is pointing out that someone isn't the only scammer a valid excuse? By your standard I can murder someone and get free by pointing out that others have done similar things.
I never bought his bullshit excuse of separate forum accounts. Inaba=Josh=whatever he is of BFL.
I brought up that there are many others deserving of scammer tags who don't have them because you acting like they're special or unique. I guess if you only spend all your time in the custom hardware forum it might seem like a big special deal to you, but it barely registers in the big picture. I don't know how it can be considered a bet when nobody even took it, there was no counterparty, so scammer tag seems a little extreme.
And yes, murder is totally comparable

. Get a grip.
The trust system has a drawback: if someone only ever scam a single person, he should be considered a scammer already, yet he could still receive high trust score, probably because he is nice to everyone else. So I believe Theymos should still hand out scammer tags.
Might be an issue, we'll cross that bridge when we get there. For now I think it's a good replacement for the scammer tag system.
