I find the credit page's narrative suspicious at best. I can understand taking commissions after being well established (i.e. Sahadou), but don't be surprised if you "donate" to a 3 month old account and nothing happens.
Hi MD admins,
I donated 20 USD through PayPal on 20 Dec 2019 around 0700 UTC. This was around 1-2 weeks before the servers were taken down, and MD has now transitioned away from PayPal. Previously, MD accounts were to be credited at the end of each month. It has now been two credit periods...
