Mythbusters/Speculations

I went over on this page:

Mythbusters/Speculations | One Piece Wiki | Fandom

One myth mentions that Blackbeard ate the Cerberus fruit; however, this theory was already proven wrong when the Shamrock sword "ate" that fruit.

So I think it need to be meantioned there.

And I have a question about the first chapter (Luffy flashback):

I remember that I heard something that the reason that Shanks lost his hand in the first chapter was something that the editor of One Piece at the time suggested. Is there any source for that?

Noticed a large sum of the whole "Romantic Relationships" myth/fact talking about this whole Luffy and Nami romance as if it was something a bit more concrete than mere speculation. I mean look, as a shipper myself I support the pairing, but that whole bit isn't to dispel a myth but toss a ton of speculation suggesting that Luffy and Nami are a couple supported by Oda.

There's even this whole little section dedicated to talking about the Romantic Comedy spin-off "Koisuru One Piece" and how it's "new" (2018 is new?) yet has anyone actually read the thing? I don't know a lot of Japanese (yet), but honestly the thing is light on the "Romantic" and heavy on the "Comedy" and you don't need to know Japanese to get that vibe. (And honestly that the thing still going strong when the rest of the spin-offs are mostly short, and often done... Impressive...)

Tangent aside, what I'm trying to say is why hasn't someone looked at all of that text and thought, "Hey, what's going on? Why is someone trying to push the idea that Oda prefers LuffyXNami in a mythbusters section when there's no real evidence to prove this?"

I'm... Very new to this whole editing thing, but I wanted to bring attention to this in some way, shape, & form; even if this might not be the proper channel to do so...
