Anonymity on social media allows users to conceal their true identity, facilitating freedom of expression and privacy, but it is also a tool used to perpetuate cyberbullying, disinformation and hate speech. For this reason, on 30 April, an artistic activity was held with the pupils of class 3ºD at IES Parque Lineal, where they reflected on identity, anonymity and cyber-hate using the Art-Thinking methodology, and took part in a mask-making workshop.
