Google Maps reviews are working like that and are often gamed.
If you pay close attention, you can spot fake reviews because they usually come from “Local Guides” (so supposedly the most trusted users).
Reddit is somewhat better at ranking and filtering spam, due to local mods, like there were in the times of web directories and webrings.
One of the former bosses of Google search explained that the key metrics they follow to consider the success of “Search” are the number of page views and the total revenue.
So if a user doesn’t find what he needs but keeps coming back it’s a win for them.
