Mass Action Incest
An Incest action is when your accounts will all action on each other. A Mass Follow Incest Action of 10 accounts means all 10 accounts will follow all other accounts in the action. So acc1 will follow acc2, acc3 ...acc10 and acc2 will follow acc1, acc3... acc10 etc. Mass Incests can be limited, so rather than action on all other items, if you set Max Actions to 3, each account will follow 3 other of the selected accounts.
