Since there is no Illuminati in 2013, no one. The Illuminati ceased to exist in 1785, and have only had one leader, Adam Weishaupt, who unfortunately died in 1830. Sorry, no one since, because there has been no Illuminati since.
A cult is a small group of people who follow their own religious beliefs. The leader of the cult is the leader who makes and enforces the rules of the cult.

No, Asking Alexandria does not support any cult or religion, it is just a rock band. And, as the Illuminati do not exist any longer (not since 1785), no one can be a member.
