--- BEGIN ISSUE ---
SUGGESTION: Contacting the instance's maintainer(s)
Hello, so I use searx, but I personally think that there should be any way to contact the maintainer(s) of a public instance (email for example). It is harder to trust this awesome service if there is no way to contact the maintainer(s).
