This. I recently got approached by a scammer on Facebook marketplace. It was never going to work but the spelling/grammar issues instantly made me think something fishy was going on.
They put plenty of investment into scamming me before I called them out, and I don't think their grammatical errors would have served to filter anyone (because it also could have just been someone wanting to buy something who happens to have bad English).
