takah, do you really think unfiltered internet use, with the sheol tachtis being at the flick of a finger, is the same as with a filter? seriously? do you know a rov who would say that the internet is so bad that it makes literally no difference? filters transform the internet from a spiritual contaminant to a largely psychological one, with spiritual side effects, such as bitul torah.
as to the OP – there’s a reason most rabbonim are not very happy with YWN and similar sites.
