I really don’t care if you donate me 0.01$ or 100$ but I won’t accept payments where nothing arrives at my account.

If for some reason you can’t or don’t want to send me a donation as a friend or with disabled payment protection (I think as I’m from within the EU this option only works if you are from within the EU as well) then paypal will take its share from your donation - it’s up to you to make sure that in this case I get more than 0.00$.

As I’ve written already, the donation amount does not matter, but it must be a positive number.
