New Hack?

Playing Ship TD today and had a player join with no name and kill us with what I call, a beserker hack...it basically looks like the player is all over the place really fast. But when it kills me, there is no name, it is blank and tells me I died. When I record it, I cannot see him in tab view nor follow him. Is this a new hack?
Regardless, I reported him, let's see what z8 can do.
I hate hackers!
Can someone tell me how I can upload a screenshot to this thread?

Thanks!
