Well, there seems to be little incentive to donate.

To convince people to donate you'd need to:

- Show what you need the money for (what are your monthly costs? Are you covering any of them yourself? Are there any start-up costs?)

- Convince people they can trust you with their money (Have you run a donation-based project before? Can you show us anything that proves you have the know-how to pull this off? Have you ever succesfully run a 24/7 JJ2 server?)

- Clarify why you need donations now while dedicated servers have pretty much always been available to the general public for free.
