@ozoned @Liberapay I have asked myself the same question. Liberapay enables monthly charging that afaik is not a feature of PayPal. The comparisons then are between Liberapay, patreon & ko-fi. I use all of the above, & so far no one is supporting me through Liberapay but if I could force my patrons on ko-fi & patreon onto Liberapay I would. Why? Nonprofit Liberapay respects privacy & our time. The others are for profit & bombard us with meaningless notifications.
