Itche srulik: Litvishe Chareidim historically have never believed their rabbanim had special powers [even if they did believe that some leaders had ruach hakodesh, it was never an obligation or considered a central part to their Judiasm]. Only Chasidim hold that belief in the spiritual powers of their rebbe is a crucial part to their Judaism.
Feif un: I don’t think the internet can be used as a definition of Modern vs Chareidi Judaism since the split between Charedim and Modern Orthodox occured way before the internet was invented. Additionally, many Chareidim also hold that the internet should be taught to be used when filtered and for productive purposes.
