Thanks for this very interesting article.
I am however extremely surprised that with a 20% mistake rate, the company is not involving any human judgement to double check. Twitter is indeed extremely important for some individuals and it feels like shutting down the account without any human judgement is causing a real damage to the account owner. Considering this, what is the legal issue the company is facing while doing this? Does the user can pursue Twitter in court? How reactive is the company towards dealing with those mistakes? And most importantly, who is held responsible for the mistakes of the algorithm?
