Why would they write "explicitly clear"?

'Explicitly is an adverb meaning to do or say something in a clear, exact, and direct way'

Surely they want to stop all requests for that content, even requests in an unclear, inexact or in-direct way. I only ask as I expect a lot of effort went in to defining that the wording of that prompt and it immediately stood out to me.
