Not 100% sure what you mean by that, but...
During a livestream, the livestreamer, DoUEvenShift, was doing ./d (He's a diamond donor.)
People couldn't figure out who he was, so they attacked him on sight, like they would any other person.
However, as soon as he did ./d, it says that he "Left the game" or whatever. And right after, someone with a randomized name logged in - Immediately after he "Left". I was able to tell that was him, and I could have targeted him (Except I didn't, and won't, since he's awesome and gave me iron donor.)
