is this really hacks ?

I'm looking at this thread and this player banned another player for hacks but the player recording hits were not registering at all, i think the player who banned the other player was lagging because not any client can fly like that over the water, its not jesus because its over the water. tbh it looks like lag in my opinion, heres the vid https://www.mineverse.com/threads/yoshadowjr-blatantly-flying-jesus-banned-chipe.134612/

 

Looks like lag to me ;/

 

Yea, Looks like lag or a bug or something but not hacks, never seen Jesus hacks like that before

 

I have already unbanned them.
