You did a good job but it's rare for someone to buy mining hardware without digging a site search, and other details, and I also didn't think scammers were stupid and lazy because they made scams so much easier to spot.
Right now, mining gear related scams are low, perhaps due to low mining profitability, but wait when the profits are up again and almost all the official stores don't have stock due to high demand. That's when you will be shock by the way people/newbies get scammed by those fake mining sites that you can see from a mile away.
