Since you appear to be an actual person working at amazon and there doesn't seem to be a way to report mass scams, I would appreciate if you could delete all items with the keywords "18650" and "9800" or "9900".
"18650" is a type of lithium battery and capacities above 4000 mah are technically impossible.
Usually the batteries with lower rated capacities are fake, too, but at least this would get rid of the most blatant scams.

There are also many examples of fake power banks, but those have varying form factors, so you'd have to calculate the volume or check the weight to make sure it is technically impossible.
