Sigh... the state of the libertarian community is not what I would like it to be. I wish you will be able to prove his guilt one day.
I certainly wouldn't do business with him, but that's because I'm more careful than some about where I spend my money. Some other guy might think it's perfectly reasonable to take the gamble.
It's much easier to do something constructive, rather than trying to prove or disprove this or that claim made on the internet all the time. This is another reason why I want to do my own thing and bring some order to this nihilist chaos. -I won't be on the payroll of TDV, Infowars or Freedomainradio, I can promise you that.
And if you could create something yourself, I think that could be a great thing.
