* A few times skimming this, I didn't understand some of the assertions and logic. For example, I couldn't say just by glancing at the photos that the card wasn't filled out on an IBM Selectric II (introduced in 1971, before Apple was founded). For another example, I see people commenting on VAT tax missing on the receipt from the German Red Cross, and also the confusion over whether it was bought on eBay or from the German Red Cross, but no mention of whether that invoice might be something that the German Red Cross adapted to work with early eBay doing the payments (at least in the US, sales tax for online purchases was very murky, and eBay punted). Also, the author seems to be ignoring cross-cultural differences, in their psychoanalytic speculation about subtleties of seller's behavior, such as seller's perceived earnestness in composing a photo.
* This article is going out of its way to publicly defame someone. If they have strong evidence of the counterfeiting and fraud that they allege, they should be going to a legal authority. Given that they decided to get Internet Points out of it, they'd better hope that their allegations are correct, and also that they can prove it sufficiently if sued in some jurisdiction. I would guess that glomming onto mob behavior ("We did it, Reddit!") won't be a good defense.
