So, I've been thinking a little and I've decided that, surely, adding benefits to MCBuild VIP's could provide additional income for the server and support development, etc. These suggestions are based around restricting normal players and allowing VIP players more options.
Please suggest improvements or extra ideas rather than give outright criticism in comments
At the moment (as far as I know) there's no cap on the amount of maps one player can create. If a cap was made, then perhaps VIP players have a higher cap or can create infinite worlds
If a VIP ends their subscription then extra worlds created are archived for a period of time then deleted.
At the moment all maps are private until a player allows white-list players to view it. If VIP members can keep maps private and normal players can make one or two of their maps private then the incentive to buy VIP could be high
As it is, I'm fairly sure that maps aren't deleted after inactivity but if this was implemented then VIP players could be exempt from this, meaning after a period of inactivity after which a normal player would lose their maps a VIP would still keep them
