Not knowing which of over 350K English-speaking wikis you're referring to, all I can do is point you to Help:Adopting a community and Adoption:Requests. Although I shall clarify that "adopting" a wiki is the process of seeking administrative rights for wikis where the local Admins are inactive or MIA. but as the 2nd link explains, being blocked on any wiki generally disqualifies you for adoption of any.

If there are active admins, then you're looking for a Promotion and need to contact them on that wiki and find out what it takes to gain that promotion.
