The vid that explains it all

i don't know... the ref tells you to stop doing something 25 times over the course of a fight.
and that thing he tells you to stop doing is illegal and you unfairly benefit from...

why wouldn't points be taken?

True, just saying, pushing off, although "illegal" is something that normally doesn't get called, so why was the ref even doing it to begin with. Peterson himself said he wasn't bothered by the pushes, what he said bothered him, was having his head pulled down.
