No, muting is not visible outside the web interface, it is not recorded on the blockchain. I don't know how much study of sociology, or for that matter, direct experience at how powerful shunning is, that you have. It's not an instant win like a punch in the face. A few weeks go by, and this individual is also shunned by others, and they start to mend their ways, or scarper off to greener victim-pastures.

Swearing neither affirms nor diminishes the linguistic skill.

You can advocate freely towards punitive measures against social abuse behaviours as much as you like. I am just telling you, as a long time victim of this, that the most effective tactic is shunning.

The thing that you clearly don't understand is that these kinds of lowlife are all about getting attention. It's not about you, it's not about pushing you down, but rather the relative position change that they cause when you act like an idiot and get upset. Buddhism is a religion where this lesson is widely taught, and look at Asia. Why do you think asians are so well mannered and humble? Because it benefits society more to just look straight past these pigs, and ultimately, become so oblivious to them it is as though they don't exist. This forces them to adopt honest tactics of acquiring attention.
