The most concrete, undisputable evidence that one is using AdvCOC is the person, who's known to have ADvCOC, has thick, flow-like haki trail coming out from his sword/fist/weapon/leg.

Everything else is up-to-debate.

Remember the immense salt from haters when that zoro CoC chapter dropped in Wano lmao good times
