Edit it and remove the /web/20160506180535/ and /web/20160506180535im_/ from the PayPal form at the bottom.
Open it and click the PayPal donate button. (I would just paste the HTML code in this post, but I suspect giving people a PayPal hosted_button_id in an editable HN post would feel kind of sketchy, as opposed to getting it from the Internet Archive.)
I'll also ask to have the PayPal button put back somewhere during the crowdfunding campaign, which would be a lot easier.
Not to mention that currency conversion is a complete ripoff. I avoid PayPal like the plague.
They lock accounts on a whim and require extensive, unnecessary documentation to get your own money back. They recently settled a class-action suit because of this: https://www.accountholdsettlement.com/
They nearly always side with purchasers and reverse charges despite ample evidence supporting the seller.
