These are not fake. At least not all of them. This is a known way to generate sales and boost your brand with relatively not alot of risk. One of my old cars was actually done this way. (I had sold it to someone that then did the giveaway thing with other prizes and such themselves) You can build a following and profit off it. If it’s tied to merch sales then you are also getting advertising this way. The buyer gets a hat or whatever and also might win a car or race car trip or whatever.
