Paying for your admin shows that you are dedicated to this community and want to support it by giving up something for it. You are not paying for your admin, you are donating money to the server to support it and receiving admin as reward for your contribution. And as the others have said, if you are not willing to make that kind of commitment, try to find other ways to prove that you want to contribute to the community. This isn't a gaming clan in the sense that members are chosen by skill and tryouts, it is a brotherhood that the members have committed a part of their lives to in order to be accepted.
