Allowed or not?

Was on the phone today (couldn't use keyboard or listen on headphones)on deagle map on gg while just camping in spawn and taking any kills that passed me by (hard to believe I got so many lol). 5 min ban (no kick) for camping in the open at spawn free for all to own me. I lol.

As far as I remember Zero said he did not care as you are pretty much a sitting duck and a free kill. What is the definite ruling on this?
