Chances are the scammers are fellow conservatives. There's a phenomenon on the right that you don't see on the left, and that's when someone at Point B on the right side of the political spectrum looks further right and sees someone at Point C, sees something crazy that they're afraid of and kinda understands it because they're also conservative but doesn't buy into it and realizes he can make money by selling some product that's suppose to solve Point C's problem. Why start at Point B? Because there's someone at Point A further to the left of B doing it to B.
That's not to say that there are not useless products on the other side, but the people buying and selling are convinced that the product is worthwhile. There's not a malicious intent to scam someone but to actually help the buyers with something the sellers use and believe to be helpful.
