<s>[INST] I need to introduce a topic in a very short time. Try to summarize the concept of dark social media in 60 seconds or less.

Here's some explanation:

Dark social media is a term that refers to online sharing that can't be tracked by traditional metrics, such as likes, comments and shares. It includes private messages, emails, and text messages sent between individuals, but also content shared through private online forums, chat apps, and encrypted messaging apps. This type of sharing is difficult to measure, as it happens outside of public social media platforms and doesn't generate publicly visible engagement metrics.

Can you summarize this in 60 seconds or less?[/INST]
