One of the attributes of Facebook (now called Meta) that attracted many to the platform, which is now the biggest in the universe (with 2.89 billion users), is anonymity.
One can be Maria even if she is Juana, or be a 35-year-old engineer from China even if he is a 25-year-old writer from the Philippines.
Officially, Facebook has a real-name policy, which requires users to “provide the name they use in real life.” In practice, however, those who are creative can go around that rule and hide their real identity.
Anonymity is not evil. It can be used for something good. However, as in all things in this world, malevolent minds are using it to do vicious acts while escaping accountability.
