The phenomenon of mass migrations to Mastodon

On the last Sunday of 2019, an earthquake shook Twitter in Spain. Many users of leftist ideology denounced that the social network was closing their profiles to censor them. One of the most influential users is perhaps Profe Rojo, also known as Al otro lado del muro, who also reported the facts. During 2019 the social network of the bluebird had already closed his account three times, so he announced that he would migrate to Mastodon.
