“Let’s start with fake accounts. We take a hard line against this activity and block millions of fake accounts each day, most of them at the time of creation. Between October and December of 2020, we disabled more than 1.3 billion of them. We also investigate and take down covert foreign and domestic influence operations that rely on fake accounts. Over the past three years, we’ve removed over 100 networks of coordinated inauthentic behavior (CIB) from our platform and keep the public informed about our efforts through our monthly CIB reports. ”
