I just took a look at the https://tumblr.zendesk.com/hc/en-us/articles/4417356885527-Tipping page on how to set up tips.

Min tip $1

You need to set up a KYC'd account with Stripe (so probably geo restricted, at least to only places where stripe operates) and anyway how is it normal that to use a service you have to open an account with their banking partner?

You don't get the tips till they reach $25

You need to be 18+yrs to use?!

Depending where you live >1% cut is taken from each tip

Hopefully we can do better!

For example it should be possible to tip a nostr account without a nostr account and with any bitcoin wallet support lightning payments.... Though I just tried tipping your post not signed in via nostrudel but couldn't get the payment request to come up.
