A long term memory is nice. But we see such similar things get exploited. Like how people will get a high seller rating on Amazon selling one product, and then switch it out for a lesser product while keeping the old seller/product ratings. So the user looks at the seller and product ratings over the past year, but at the point and time they choose to buy, they are going to be burned and the bad seller makes off with the money.
