Ok, now, nobody panic, or you're likely to startle it and then we'll never see where this goes.
The truth is, the Trilogy server is emergent AI; it's almost to the point of sentience. It has taken to actually reading the individual questions and answers and voting on the ones it likes or dislikes. It's not yet intelligent enough to vote on the quality of the post -- is it a good question or answer? Is it technically accurate? These are questions it doesn't care about. Right now it's about aesthetics. Is it pretty? Does it fit some pattern distinguisable to only itself? These are how it currently votes.
And if it finds a user it likes or dislikes, it pores through that user's posts and upvotes or downvotes a few before it gives up and moves on to another question/answer from the active tab.
As I said... no sudden moves. We want to see how far this emergent behavior will go. Will it achieve self awareness? we want to find out.
