The only people you find complaining on Bitcointalk for the most part are competitors or known trolls like Entropy, Bicknellski, etc...
To answer your question though: No there is nothing valid they bring to the table that qualifies as a scam. Just angry butt hurt trolls who can't stand the fact that all their idiotic "predictions" and false claims turned out to be lies and they are exposed for what they are. So they try to flood the threads and forum with more junk in hopes that people will forget.
Respectfully, you've been just as guilty of that. It's been a very eye opening thread, to say the least.
I have no dog in this fight, just wish there could be some sort of dialogue..."hey, this is what you've done wrong, and here is the evidence" and counters of "We haven't been perfect, and here's how we're working to improve."
Name calling doesn't restore BTC or help reputations.
Josh, as an early adopter of Bitcoin should be enormously wealthy, and a very happy camper. Instead he is filled with rage because essentially everyone in this community considers him to be lower than dogshit.
Please, don't offend the feces by placing them together in the same paragraph.
The feces does not feel compelled to lie and dance around facts in an attempt to confuse folks.
The feces feels no rage towards customers though sometimes is warm depending on the season.
The feces does not experience malice.
The feces does not experience shame. (well neither does Josh, one thing in common)
The feces feeds trees, the grass and makes the world go round.
Josh, stammers into rage filled tirades when confronted on facts, sometimes smiles, often confuses and delays his customers. When he finally serves a purpose, the time has already passed.
--Can you imagine all the fights he has caused with peoples wives/husbands while he delayed peoples pre-paid miners?
--Can you imagine all the self loathing he inspired in people, who endured, when they bought into the pipe dream that turned into a nightmare?
--Can you see the scope of the endless frustration and disappointments as things dragged on and others with less...provided more?
Don't diss the feces my friends. It has its part in nature. Scammers/liars do not. They serve no purpose. They make nothing in nature grow or blossom. They just rip people off and leave a trail of tears and anger.
When you see Josh with his swagger, just nod your head his way...in a sort of buddha inspired "knowing" and pity. He's doing the best he can muster.
