They literally only make sense if you already have the chapter.
It's stupid.
People like that are the reason the entire world is shit: "I know what's going on, but I won't tell you, because I want to lord the information over you."
Nothing wrong with wanting to withhold spoilers to protect yourself... but, the people who just create drama after drama, and then pretend like they don't want attention? The people who say they're worried about getting found out, while constantly playing up drama if people leak before them?
Oda wrote the story, leakers and theorists are just mooching off of it. Go write a Mean Girls/One Piece crossover if all you want is to fill One Piece with stupid ego-driven drama.
We're here for One Piece. We'll get One Piece without you, stop acting like you wrote the story because you're time-gating leaks, LOL.
