I believe that the tense atmosphere is created not by some magical, incomprehensible means, nor by some abstract things, but by quite specific actions. And these actions may contradict the Portal Rules regarding respectful treatment of each other.
And, by the way, it's not necessarily true that if someone starts claiming that they are not being respected, or that someone is to blame, then that is actually the case. This noise may very well be a defensive smokescreen, and in reality, it was exactly the opposite.
All such actions can be examined, and it can be determined who exactly created the "tense atmosphere," and, most importantly, what specific action they took, so that a warning can be given to that player to prevent such nonsense from happening again in the future. And the situation can be brought to a state that complies with the established Rules. This is the task of the tournament judges and the Administration Committee.
And if someone says that this is nonsense, that there are more important things in life... Then I would argue that, in my opinion, many of humanity's conflicts arise from such minor things in real life. One person says something, meaning one thing, and another person interprets it differently. And in that case, he was also saying something strange, and besides, Petya (Vasya) was speaking badly about him, and Petya (Vasya) and I are friends, so I'm sticking up for my friends. And it escalates. The essence of the matter is no longer of interest to anyone.
It's simply that everyone is too lazy to deal with this. Although, for myself, I have identified approximately 4-5 typical situations that were not addressed in the past and are repeated here time and time again, year after year. Everyone has their own "favorite sore spots," and many get upset and worked up over nothing, when they could have calmly discussed and reached an agreement in 5 minutes if they had simply carefully reread what the other person wrote, focused on the facts, discarded their fears and fantasies, rigid beliefs, and stopped getting worked up because of their own rigidity.
And there are not an infinite number of these "sore spots"; in fact, I think there are very few typical ones. In half a year or a year, you can deal with them as they arise.
