13. A common contribution may, at the discretion of the individual who maintains the hardware, the software, and the data that make up the virtual space, be required in order to maintain the existence of avatars who enforce the code of conduct and to maintain the hardware and the software and the continued existence of the virtual space. Avatars have the right to know the nature and amount of the contribution in advance, and said required contribution should be equitably distributed among all the citizens without regard to their social position; special rights and privileges shall never pertain to the avatar who contributes more except insofar as the special powers and privileges require greater resources from the hardware, software, or data store, and would not be possible save for the resources obtainable with the contribution; and as long as any and all avatars are able to make this contribution and therefore gain the powers and privileges if they so choose; nor shall any articles of this declaration be contingent upon a contribution being made.
