Session
It's hard for a platform to have meaningful, useful ratings/reviews without both
substantially Knowing Your Customer, engineering to detect manipulated reviews,
and responding in a nuanced way -- to increase a fraudster's costs,
and not just train them to hide better. Lots of examples of diverse
platforms not doing a very good job of this. (I'll also talk about how this
knowledge sometimes leads platforms try to manipulate their own
customers to maximize their sales).
