For Moira these seem to be personalized posts but they're not as good as Rina's to be honest. I feel like Rina's posts (staff who ran it) were more personal because it wrote things that were mentioned in the thread whereas these ones could easily be seen as a bot post because they seem generic enough but I don't know...

Edit: Looked at Devin and no personalized posts--what a shame.
I haven't checked Carl but I've got a sinus headache coming back on so I will look later. But I'm guessing that it's based on the leaderboards? Rina and Moira are in first and second place so Rina would have more posts, then Moira...
Though a few personalized posts here and there would do wonders for morale. But this seems to be a new level for NPC posts.
We go from botted posts > personalized posts (usually making a post about the topic at hand, but not to a specific person > NPC interaction.
As much as I love NPC interaction, I will take personalized posts over botted posts any day.
