Hacker found - Video proof

[Guesswhat]

I have no control over this vid and the character names are all visible, but not in vid-title. Hope I'm not in trouble for this...

As you can see, BLM gets out of reach/invisible. BLM can target us but we can't target the BLM. This is clearly not a bug but intentional hacking (or whatever it's called).

EDIT: The same person appeared in the next fight I was in as well. Did the same thing there apparently, though I did not see it.
