This is gonna be a rant, so if you don't want to listen to me rant about Book's unfair treatment (and FreeSmart as a whole) then here's your chance to go back now! Now that that's out of the way, it's time for my first non-Roblox blog!
Proof?
Book has been UFE (up for elimination) 5 times in a row in BFDIA. CloudYAY (what I consider to be the new FreeSmart since it has Pencil) also almost managed to escape elimination in TPOT, but no, they just had to be tagged by X. Meanwhile, Pin is only starting to be rigged against now, and I can tell the writers aren't happy about doing it. The only reason they're trying to get Pin out is that she said BFDIA sucked in BFB, and in the writers' eyes, it wouldn't make sense for Pin to think it sucked if she won it. Now, you might ask: "Is this the reason for FreeSmart's unfair treatment too? To get out a certain character because it was implied in the future?" That's what they want you to think, luckily I have proof that that's invalid.
Book is allowed to win BFDIA, writers!
What the writers want you to think is that less than a second of BFB 13, "Return of the Rocket Ship" means Book is unable to win BFDIA without breaking the timeline. The scene specifically is Book looking herself up in herself, and for a split second on the left in 13-33.fla (BFB 13, Scene 33), a definition for "Battle for Dream Island AGAIN" is shown: "Battle for Dream Island AGAIN - was supposed to be won by Book."

If you check the episode's video, not "Book" nor "Battle for Dream Island AGAIN" are show in their entirety.

If they actually cared about timeline errors as miniscule as this, Gelatin should've won BFDIA since Announcer said Gelatin had never been eliminated before BFB 30. Rigging BFDIA so Gelatin always had immunity would cause alot more backlash though, so they didn't. But Book? Most viewers won't notice if Book is repeatedly UFE since episodes are over a month apart, making her an easy target. And if you dare challenge their bias? "Battle for Dream Island AGAIN - was supposed to be won by Book." If you really wanted to give them the benefit of the doubt and say that it's only for timeline reasons, then you also have to accept that they only do it if they care enough about it, which still raises suspicion on why they wouldn't care enough for Gelatin but would care enough for Book.
We can fight this.
The writers can write, but only us voters vote! If we continue liking Book and disliking our other dislikes, Book can win, despite this obvious rigging! So please, like Book's video and dislike whoever you don't like if you think Book is being treated unfairly, I'd really appreciate it.
Final Thoughts
As a Book fan, figuring this out is really sad. I do have some hope held out since as of writing, Book has the least amount of dislikes. This blog post will probably change nothing, but aslong as the writers don't suddenly villainise Book (which would mess up the timeline for IDFB so they probably can't) then Book should be fine.
