They still show up as text, but they don't get counted in the average. If Amazon at T = 0 know which reviews are legitimate and which aren't, someone who consistently gives five-star reviews to shit products could have their ratings lowered in importance. You could go all the way with this: look at my reviews, and then only show me reviews made by people with similar tastes.

A good idea. I'd wager that a high proportion of users who join these "rating review" schemes are accounts that rate 90+% of their items as 5 stars.

If you check my Amazon account, I don't even rate most of my purchases.

It's a rather low sensitivity metric but one that has some value.
