Well, actually I'm about to report this thing but I'm afraid I was wrong, so I just want to clarify it here before reporting it.

So here's the case.

I found someone, let's call him X, in public ABD who keep enter and then quit or disconnected by no response. Whenever X enter the server my game suddenly not responding and then my game pinged or caused one player who is in the same server pinging. I have some screenshots about this.

So is it a bug exploit or what? I never experienced something like this before.

Thanks before.
