Anyway, jokes aside I think GOATIK is lying on the Kiz spoilers.
Redon is much more trustworthy, and he said the chapter starts with Kuma flashback following the end of last chapter. Why would Oda just come over and drop the info Kizaru is KO'ed here ? And it makes no mention of Luffy who fell to the ground at the same time too.
TLDR: GOATIK is an attention whore who mixes fake spoilers with real to generate buzz. AKA another run of the mill OP leaker.
