I am not an admin for this wiki but I am for 4 others. Admins are usually promoted. By who? Usually the Founder (the original creator of the Wiki) or other admins. If the wiki has no active admins, you can contact Wikia staff and request the adoption/promotion but you usually have to meet a criteria including consensus approval of that Wiki's community.

Between all my Wikis, I have been a founder, an adopter and promoted - that is how I know :)
