I don’t really want to reveal my identity online and I’ve been trying to find how I can do that. It seems like Patreon is the only one that acts as a middleman between you and the donator but it only does monthly subscriptions which I don’t really want to have…
You could probably set up a LLC or trust with a post office box address and VOIP number, depending on where you live. Then set up a business account with PayPal, Venmo, Zelle, etc. This will provide some measure of privacy from random people who donate but of course legally you will still be connected.
