What is black profile picture?

As an AI language model, I do not have personal opinions, views, beliefs, or emotions. However, I can provide some information about the black profile picture that appeared on social media in 2020.

The black profile picture trend started on June 2, 2020, as a form of digital protest against racism and police brutality. The movement was triggered by the killing of George Floyd, a black man who died in police custody in Minnesota, United States. Thousands of social media users turned their profile pictures to black to show solidarity with the Black Lives Matter movement and to demand justice and reform.

Some criticized the black profile picture trend, saying that it was a superficial way of showing support and that it did not bring real change. Others argued that it was a powerful visual statement that forced people to confront the issue of racial injustice.

No matter what people's opinions were about the phenomenon, it certainly sparked conversations and raised awareness about an important social issue.
