I notice that some people are really micro managing Tawsix. Early on, I asked for name and address and Tawsix didn't want to tell, which is fine. Investors shouldn't have invested if they weren't okay with that. If Tawsix wanted to scam people, he would obviously be long gone by now (under that identity at least), so why still all the mistrust?
Each time you ask Tawsix unneeded questions, you are the one loosing money if you are an investor because it takes time to read and respond and that time could be spent on creating value instead.
How much value could he have created while he was waiting for mining rigs to show up?
I'm not in the 'he's definitely a scammer' camp, but when you ask for 3750 BTC from strangers (about $22,500 at the time he asked) maybe you can find the time to spend 15-30 minutes a day answering emails. It was complete lack of transparency that caused me to sell off my shares when the price went to 1. If there had been transparency, I would have bought more when the price went to 1.
Instead lack of communication presents a vibe, perhaps unintentional, that's either "Shut up, I've already got your money!" (on the positive side) or "Scammer" (on the more negative side). And I think that translates to the fact that there are significantly more asks for SIN than all other GLBSE offerings put together, which should be a warning sign to the CEO.
