IIRC the cell phones during SOTU with POTUS revealed the possibility that bad actors were using online collaborative games, like poker or bridge to communicate. We also are aware that a common gmail or google document was used to drop and pick up messages. I dont have a twattter or FB account, not do I game. But if someone can connect users to the twat account, then to an online game or you tube vid comment section, etc… Gamers would know what to look for if the connection was a game.
