If I would buy that Lincoln and I would place it next to the real ones in my album then most likely the spirit of Abe would raise from his Memorial and haunt me forever after

On the other hand, since he has as we speak, only 30 bad reviews on
ebay, perhaps that could be addressed by the community of honest philatelists? ... by spending $5 one could buy a cheap item inclusive of postage inside US and then post a review

To my knowledge, if a seller gets a certain number of consecutive bad reviews then
ebay is reviewing that seller account.
