Remarkable claims require remarkable evidence, claims that are made without evidence, can be dismissed without evidence.

If a handful of people complain out of thousands and there is no hard evidence, then I see no reason not to just dismiss it.

On what grounds do you consider a claim "remarkable"?

This also isn't a standard of admittance that would work terribly well for minorities.
