I'm not sure if this has happened yet, but maybe if your idea works out with denying guests access and allowing logged in users to view the site, maybe you could allow users that have donated to have first preference on the space (hey they donated, why not do them a favor).

This maybe a stretch but maybe only allow certain features of the site to be used after 20 posts or something else, like a time limit saying that you have to registered for X amount of days to use this feature.
