I've seen a lot of people advertising their shops saying "Buy something from my shop and I'll give you a good item." It's quite obvious that these are all scams, and I tested this (I bought an item that I would've bought anyway in order to prevent getting completely scammed) with a person named 24hour24. When I told them I bought an item, they just said "Did you?" and locked me out of their den. I didn't get proof of the scam, but I feel like the entire "Shop trust" scam as a whole should have a page.
