As Marshall points out, having a solid, consistent history of accurate, relevant and representative submissions is a key criteria for consideration. If you have a history of poor or rejected submissions, which indicates a lack of knowledge or understanding about the area, that's going to kill your chances of even being considered. If you submit data that is inaccurate, counterproductive, misleading or would serve to lower the quality of the database, you certainly would not be entrusted with the ability to directly maintain the database, as you'd wind up doing more harm than good.
Generally speaking, of course.
