"Donation-supported" means that the MUD accepts payments, but its policies exclude providing in-game benefits in exchange for them. "Donation-drive supported" means that the MUD accepts payments, with policies excluding providing in-game benefits in exchange for them, only at specific times for specific purposes (most typically hardware upgrades), and does not accept payments at other times.
