You can certainly request it be closed as a spam wikia through Special:Contact. A staff member will review it and close it if they agree with you.

If you just want a sandbox wikia it would probably be much easier to create a new one rather than trying to adopt this one. But in order to adopt it you would need to meet the regular criteria of contributing to content and building new content there.
