The Arcane Library, makers of Shadowdark, posted recently about having to turn off AI chat bots posting in their group. A feature neither desired nor asked for.
May want to check any groups you run, Facebook or not.
Last time I ran a game for kids under 12 they both said at one point they were trying to get their PCs killed.
Understand that it was not the norm, but not that far off. Most times I find kids are used to character death.
