"Children were presumably glad to be off school – until, that is, an app called DingTalk was introduced. Students are meant to sign in and join their class for online lessons; teachers use the app to set homework. Somehow the little brats worked out that if enough users gave the app a one-star review it would get booted off the App Store. Tens of thousands of reviews flooded in, and DingTalk’s rating plummeted overnight from 4.9 to 1.4."
From a great piece in the LRB.
