1) Send message to inactive users "Hey, I'm a mod for dad's community, I noticed you've been inactive in the community lately, is it because we're boring to you?" Don't directly ask them "Why aren't you interacting" "Is there any reason for this", instead throw a little joke like "is it because you find us boring now?" "Did the group not live up to your expectations?" 2) Send another message "Hey ____, the community would love if you were more active !" 3) Create short video asking users to participate more within the group showcasing what's going on while they're not active.
