Amazon has been a big driver of anonymous business. They don't tell the customer who the real seller is, yet, when sued for liability, they claim they are merely connecting buyer and seller. Even when Amazon doesn't know who the seller is. Amazon fought liability up to the Pennsylvania Supreme Court, then finally settled when it looked like they were about to lose.[1] Amazon thus enabled an entire fake product industry.
We see this all the time with NFT scams. Especially the kind that are fund-raising operations for something not built yet. Those are public offerings, and when made to US persons clearly require filing with the SEC, with all the usual disclosures and financial statements. The SEC shut down the Initial Coin Offering industry back in 2018 for that sort of thing, but hasn't gotten to the forward-looking NFT industry yet. Probably because the complaints haven't started coming in yet.
