I wanted to give a tiny donation ($6, not rich enough for more), but unfortunately gave up, because the donation system asked me for my full address, zip code, phone numbers e‑mail, and they was a note below, saying clicking on the submit button, means I agree they give/transmit these personal informations to anyone they wish, which is a big no‑no to me.
Would be better if there could be a less intrusive donation system, which will just ask people for their payment card name/surname/numbers, and that's all, which is enough for an on‑line payment, and so I believe, for a donation.
Donating should not mean “giving PayPal an opportunity to get personal informations and sell them to who‑know‑who”.
Thanks for the feedback. I've offered WePay (which requires less information) before but nobody used it so I removed it. Do you have any idea what payment system to use? Would a Bitcoin donation suitable for you?
