I remember at the time the general consensus, too, was that she was intimidated suddenly being in a server with people who had much more to say about the books assigned for that week/month/whatever than she did - actual intelligent analyses, too, not just "WOW the VIBES were so IRIDESCENT, the author really captured EVENTS and EMOTIONS, I've never seen this in a book before!!"
She barely gets away with that bullshit in IG posts/YT videos where she can just ignore the comments, never mind a server where engagement would be much more expected. It wouldn't be long before even the people who kiss her ass wouldn't be able to deny that it's all performative, and that she skims at best (or probably just reads summaries/reviews and regurgitates what they say).
