Sensor < Genjutsu

[Rikudou Tobi]

I remember when a certain someone tried to give an excuse on SM users being able to "counter" ocular genjutsu by themselves. Funny isn't it?

So i've heard this quite a lot and im curious about who started this or what is this information coming from?

Where in the manga has a sensor been "Immune" to genjutsu. More specifically when has a sensor been capable of sensing their ownselves being caught in a genjutsu?

Please enlighten me

Couldn't Karin?
