Ok, I've never seen this sort of audit before, with the digital signing and all that, and I've invested in a few ICO's so far.
Looks pretty legit to me and I agree with the person who said that it looks like these guys serious.
I understand that this is a special ICO giving the refund and the bonus, and it's interesting to see that the aspect of anonymity is cleared up by actually having a face and name put on this even if it is not an official team member.
