I pay you money to perform a service, you take the money then you tell me you won't do that service for 6 months. If it had happened to me, I'd be quite angry. This is what Paypal is doing.

I understand their overall procedure to avoid abuse, absolutely; but Diaspora is a somewhat famous project, an absolutely legit operation. You can say what you want on their deliverables, but it doesn't matter: PayPal got a nice cut out of donations to a public and very well-documented project, then turned around and said they'll keep it all for an extra 6 months.

That's not cool.
