Well shit, I think I'm an AI, I write like that all the time because otherwise I start repeating words. For that matter, so does Proctor. Is TVA an AI generated glowop?
A former professor of mine accused me of using AI in my writing, the guy was using one of these websites to check people's work. Shut both him and our asshole dean up when I provided them with all of my drafts and an editing history. ABSOLUTELY take this with a grain of salt, these tools are not reliable in the slightest.
I'm on the fence here, I agree that it's really formal coming from Millie and is out of character for her; but this was also a special moment for them, and there are a lot of eyes on Niji at the moment. I can see her coming up with those posts in advance and using PR speak on purpose because that's how meaningful it was to her.
...yeah that tracks, that is patented Milllie passive aggressive right there. IMO she spent some time on putting together a formal thank you message and is now annoyed that people are calling her out for typing differently.
Fun fact, both her and Enna go on /vt/ regularly by the way (as if that notorious discord 4-chan stream wasn't proof enough). I've seen a couple things on /vt/ before that suddenly got brought up on stream. They always provided another source for it (oh I saw this on twitter, on youtube etc) but it gets kind of obvious after a while given that a lot of it gets posted on /vt/ first. They're dumb enough about it that someone could probably bait them into TVA, assuming that drive-by idiot @hwaorang or whoever wasn't Millie in the first place.
...Also assuming that they weren't already somehow related to the local Discord cabal/grooming dungeon. Which is a big assumption now that I think about it
