Well, in fairness they DID look like riders in black.
And if their disguise keeps people from knowing they're actually 9 ghoulish-ghost-faced-killers whose bodies should have decayed centuries ago, then I'd say 8ts pretty damn successful.
That said, it is a bit like Hafþór Björnsson trying to disguise himself as a taxi driver in Taiwan. He may technically have the getup right, but he definitely doesn't have the presence of a taxi driver.... More of a mountain-like object.
