Thanks man, yes the UIs look very similar with a text box and PWYW payments, but the value props are different. Buymeacoffee's core offering is accepting donations while ours is messaging.

Thanks man :). There are no refunds, because messaging is not a standardised service - meaning senders cannot be assured of a solid deliverable(hence PWYW).

Creators might send great responses to cheaper messages, if the message is interesting and might not respond at all for a high paid message if it is something that takes their privacy away.
