What does the green dot symbolize on Ashley Madison?

The green dot on Ashley Madison symbolizes online status, specifically indicating that a user is currently online. On many social platforms and dating websites, such indicators provide users with real-time information about the availability of others. In the context of Ashley Madison, which markets itself as a service for people seeking discreet extramarital or otherwise secretive relationships, the green dot helps users to identify and communicate with members who are actively using the site at that moment, thereby facilitating immediate engagement and interaction.
