I asked them, if Whonix could become a business partner. (become business partner link on their page)
They answer was no.
Dear Mr. Schleizer,
Thank you very much for your interest in paysafecard.
Unfortunately we cannot proceed with your application since the offered products are restricted by our compliance department.
We wish you the best of luck with your web shop.
I’ll ask them if they mind if users would voluntarily [of course] send the raw code.
