Just like demands of "Where is your evidence?" demands of the form "Give me some examples?" are often best left unanswered.

In usual practice, there are many useful techniques that don't try to clarify the situation. But on this forum it's also possible to actually answer with similar efficiency, even if not in an expected manner, for example "I believe absence of citable evidence is not a problem here" or "Not interesting enough for me to discuss further." That would be an actual reason, out in the open.
