You might be one of the people that down-voted my submission. This is probably a language problem, I don't think the original MIT license is a permissive license at all in this case.
It sounds like you meant something more like a public domain dedication like CC0, which is about the only way you can go more permissive past the likes of MIT/Apache2/CC-BY.
Creative commons specifically calls CC0 an "alternative to our licenses" [1]
