Do you remember a single time where ANY leaked info got overlooked? In the series where EVERY WEEK, EVERY SPOILER IS SCRUTINIZED TO THE MILIMITER?
I wouldn't assume malice here. When people start creating conspiracies, that's when things really go off the rails.
My best guess is that Carrot's part isn't particularly important to the chapter in comparison to the other information, so leakers aren't really paying attention to it. Or maybe it just represents a perceived lack of interest in Carrot info in the eyes of the leakers.
Who knows, I just hope Oda does something with her. Her emotional arc is tragic.
