“open internet”.
How do yeshivas determine who does and does not have internet in their home and if they do have, have proper filters etc…
Do they employ a team of crack agents who infiltrate homes when everyone is out? Do they roam the streets with smartphones and tablets looking to find open wifi, what it connects to and then work backwards to the modem? Do they subpoena Verizon and Time Warner Cable for lists of their fios and internet subscribers? Do they have ruach hakodesh?
