The big problem with Torah scholars that are demons is they pretend to be friends, but because they are demons they actually try to cause harm when they are able; and at least never help.
I mean to say that though the subject of Torah scholars that are demons is not well defined in the Zohar and the Ari, still in the writings of the Ran from Breslov it is easy to see what the terminology means.
For example in the stories of the Ran [from Breslov and Uman] you can see he uses the term as in מזיקי עלמא or what is called "mazikim." that go around trying to cause harm.
One important point that Rav Nahman brings is in his major book vol 1. 61 where he says the major blame is on people that give to these demonic Torah scholars a kind of pseudo ordination.
True ordination stopped in the middle of the Talmudic period. This is the reason Amoraim from Iraq were called "Rav" [as in Rav Yehuda etc.]
The trouble is it is just too easy to ignore this problem. But that just aggravates the situation. To me it seems best to deal with the issue decisively.
To me it seems that this comes under the category of rebuke that one knows will not be accepted. Still in some kinds of cases one is required to give rebuke anyway. I saw this in the אבן שלמה of the Gra where it is brought down that there are situations where one must give rebuke even where there is no chance of it being listened to.
It seems that this is one of those cases, because without at least someone making the problem known, too many innocent people fall into the trap.
[I do not mean that one should always give rebuke as the Ran from Uman makes clear in Vol II:8. Still, there are times when a situation has gotten so out of hand that one must make it known. ]
