Wait for a few months, then try adopting again. If you don't get blocked in those months, Wikia staff might accept your adoption. Like Merrystar said in her blog, if you were blocked a long time ago, but have been making good edits on other wikis ever since, you may be able to adopt. They don't judge the requirement based on "Has this user been blocked?". They do it based on "Is this acceptable behavior for an admin?". So, if you were blocked many months ago because you did something, but have been making good edits since and then you make the adoption, you may still be able to adopt the wiki.

About the other two wikis you're blocked indefinitely on, you don't exactly need to be unblocked to adopt. Just try waiting a few months without getting blocked on any more wikis, and then those blocks might not matter anymore.
