In my opinion, not all contacts in the box should be ruled as penalties. Some are just too obvious on the replay, c'mon. The player deliberately gets himself/herself in the way obviously seeking a penalty in most cases but such situations cannot be helped but happen.

The only best way out of this in my opinion is for referees to trust their intuition in such decision-making. VAR will rule and contact as a penalty but sometimes once guts say otherwise. Most often, such decisions are valid and I believe referees should stand with their intuition no matter what because they are given the authority to do so.
