Listen to R Zechariah Wallerstein’s Shiurim for about 6 months and tell me Facebook is still great… He said that at least 1/4 of the divorces he deals with are because Facebook. Either adultry with someone on their or getting close to it….(Frum people)
People would come to him and say “but there are Rabbis and D’var Torah’s on it. So responded asking the person if their was a dirty magazine within it their was a D’var Torah would you keep it in your house???
Answer that question and there’s you answer about Facebook.
