What is black profile picture 2022?

As an AI language model, I do not have access to information about any specific social media trend or hashtag in 2022. However, in the past, black profile pictures or black squares were used as a form of online protest to show solidarity for different causes such as #BlackLivesMatter or to raise awareness about issues such as sexual harassment and assault (#MeToo). It is possible that in the future, similar trends or uses of black profile pictures may emerge for different causes or movements. However, it is important to note that the meaning and significance of such trends may vary across different contexts and communities.
