I know that some players might describe me under that heading because I often free haul so perhaps I'm biased. But then there is no unbiased answer to this question.
I don't mind if someone or multiple people are free-hauling during the 6 eras. My objection is during End Game. That is a competition between cities. Doing stuff to deliberately screw up another city to help yours to me is wrong and should not be allowed. Haul in your own region only during EG. My opinion.
