Reminder of my own: I won't ever sign up for auto-debit such as #Patreon or #OneDollarPatreon, but if you make sure you have a number of different ways to support you, I may occasionally toss you a few dollars.

I had the experience of #PayPal grabbing funds from my bank account to send to someone I'd done business with once, three years earlier. When I protested the unauthorized transfer, PP said that since I had done business with them before, it could not be unauthorized.
