We recently ran a story on a Brazilian supposedly possessed by a dybbuk who tried to have it exorcised over the internet. The ghostly squatter has proved resistant to rabbinic efforts to dislodge it even after the man was brought to Jerusalem.
According to web chatter, an excommunication order was put on the dybbuk by the very-strictly Orthodox Rav Moshe Sternbuch of the Eda Charedit. But pouring cold water on the rumours, he told the VosIzneias newsite that the possessed man is sick and ought to see a doctor.
