In Clash of clans, while viewing members in my clan, sometimes there is an icon to the right of the name that displays a person behind a person. What does that icon mean?
Based on my observations, I think its to show who you have added as a friend within the game. If you look at your Social tab, you will see all you have added as a friend. Those names should match the ones with that icon in your clan.
