I have also checked here the duck test and read guideline for appealing as well its says 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 a person can identify an unknown subject by observing that subject's habitual characteristics.

The duck test does not apply in non-obvious cases. Unless there is such clear and convincing evidence, editors must assume good faith from others.
