That makes absolutely ZERO sense.
If you're willing to send the money to Bitcoin Foundation if they sign the message with their BTC address, then why can't they just do that and then you send THEM the bitcoins? That's totally and utterly inconsistent.
Please Deprived, since you have a horse in this race, why don't you just armchair quarterback the whole situation and we'll let you get all of the nastygrams.
It's an idea, someone else's idea.
I think the point he's making is that if you're willing to send coins somewhere, ANYWHERE, based on btc address sig alone, why isn't it enough to do for all of the addresses. I mean, it is entirely possible that Nefario created a bunch of small accounts where users will claim to be legitimate, and then trick you into sending coins to the Bitcoin Foundation.
Perhaps this is all a Bitcoin Foundation long con after all???
