Actually the real problem is that people turn many threads into a pointless wastes of time ... and then keep posting the same thing over and over for months ... like some mind numbingly stupid belief that no one knows or understands that a certain company is completely unable to deliver hardware on time
Only they can see this and thus they must post this same information a hundred times in each thread ... and make themselves look like some sort of psychotic stalker ... and then start posting falsehoods since they themselves have realised there's no point posting the same thing over and over again ... so why not make something up ...
Bottom line, I see no real problem with posting negative stuff about companies, however, there are a small number of accounts on bitcointalk that if they were deleted, that would get rid of most of the "OMG I gotta post it again today coz no body knows what I know and I must educate all these fools who read this forum ... who didn't read it yesterday" crap these threads are full of.
wow I couldn't agree more with this one
This is proven by the fact that there are noobs (plenty of them) who don't know any better and pop into the forum wondering "what is going on here?!"
In effect, disproving Kano's vision of reality. (Go to BFL forums for a perfect example; they tend to import alot of BitCoinTalk talking points over there...slow but steady.)
I am sure affiliates of certain companies would rather the noobs be informed by the ads displayed, rather than by people who have been through mybitcoin.com, pirateat40, mooncoin, Zhou Tong, and others. Every day, somebody posts on the forums "I ordered, but I can't get a refund". This is untrue, but there is a convoluted process for obtaining one. The same questions being asked over and over can be addressed by sticky threads.
Making a specific forum for vaporware product announcements (no working prototype verified by a trusted third party) would cut out 90% of the nonsense. Or just put all those threads in Mining Speculation. Also, for people who complain about content from a "small group of users" should be introduced to the IGNORE button. Press it 5 times and the forums are magically cleaned up!
