I have given him a loan twice, got repayment for both. Although, I do think it's rather odd to ask for loans so often, and sig campaigns don't pay out that often so it makes we wonder how he repays so quick.
Stunna's signature payment is due on 17 July, which is on Friday. I usually try to buy bitcoins for some of the repayment. And I don't think I would request a loan for a very long time since I'm now in Stunna's campaign.
