So, let me tell you how I deal with blocked targets:
First, I acknowledge that every being rightfully owns itself and therefore has a right to privacy. This means that I am only allowed to breach defensive measures if the being itself doesn't respect the rights of others. Because in natural law, a being that violates the rights of others doesn't have the right to privacy.
So, you first have to look whether there are victims of the being you are looking at. Probing for victims essentially is a DMP (deep mind probe) that is always possible without violating rights.
If there are victims, defensive measures get colored (I work with colors). A rightful shield, meaning there are no victims, always looks blueish to me. An unrightful shield, meaning there are victims, becomes reddish.
I am not allowed to penetrate or circumvent blue shields. Going against a blue shield makes me the aggressor, because there are no victims and therefore it's not a situation of defense. Aggressing against others always is a violation of rights.
But I am allowed to penetrate everything that looks red, because red means I am helping the victims and are therefore on the defensive side, which always is a right.
If the ETs help Farsight to burst through blue shields, they are not free will beings.
Farsight doesn't make the impression that they consider the morality of remote viewing at all. They don't respect privacy, because they don't know how to distinguish correctly between right and wrong. Yeme, for instance, breaches every shield like "a bull in a china shop". She is reckless.
