> they are not "donating". These "customers" are buying toys, which are then being sent to other people on their behalf.

It was a mistake for Regretsy to phrase it that way and it devolved into a mess from there. It started as a real donation to pay for the "cause" of giving toys to kids. Paypal's first complaint was that the recipient of the donations (the Paypal account holder, not the kids) was not a non-profit, yet their policies don't state this requirement.
