Aren't you basing that off that one game last night? I don't remember it being particularly unusual in that respect otherwise.
I agree with @StephenH that players will push the limits they think they can get away with, it'll be the same teams as the imaginary yellow cards etc. Need the ref to stand up to that.
It's human nature though. The natural response to micro management and bureaucratic barriers is to rebel. If you want people to behave, you use the privilege and responsibility method.
