When I talk with certain people, I perceive a very clear though subtle message: "I am the good one, I am the one who is right, and you are not."
One can be wrong in their perception, so I do not act right away.
Beyond a certain threshold of interactions confirming the above trend, I consider it safe to assume that the person in question does not deserve to be considered a good person.
So I block them.

Great option :)
@forza4 What you say is very important. It is indeed very important to be wary of oneself. I can easily be wrong, and I can fall in the pitfall of believing that I'm right.
But I never use subtle mechanisms with anybody. It disgusts me. And I always try never to offend my interlocutor.
It's that feeling of disgust that helps me very much.
By the way, it is the same feeling associated with the perception I mentioned in my first toot.
