Ask the admin on thier talk page or message wall, either on that wiki or this one.

If they refuse or even don't respond, you're done. You're not getting unblocked.

Also, realize that just because you were blocked doesn't mean you can delete "your" content there. When you contribute content under a Creative Commons license, it isn't yours. The rest of the community at the wiki decides whether to keep it or delete it.
