The duck test—"If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck"—suggests that something can be identified by its habitual characteristics.
The duck test does not apply to non-obvious cases. Unless there is evidence which proves otherwise beyond a reasonable doubt, editors must assume good faith from others.
