I do not know how to block internet because im in college and my parents dont put a filter on my computer otherwise i would tell you how to. Its VERY important for you to put filters on your childrens computers. I cant tell my mom its wrong not to have a filter on my computer because thats not kivud av vam otherwise i would.
frumnotyeshivish – I am also somewhere enventween frum and yeshivish and yes we SHOULD have filters on our computers. Just because the goyim have computers without filters and do not watch what they are doing does not mean we as Jews shouldnt.
