there are free software to block porn,keylogger,filters on new modems/old as well, isp's most anyway before connection as this stuff if you want a filter on.
i agree and have said it since my first son was born if parents acted as parents you would not need anything. were i live you got more dirty girls at 9 than you have in the Philippians i tell ya that and most have said its porn its the only way they find out about sex cos there mom/dad just wants the child benefits and tax credits.
ive had fight's with people due to them doing stuff like this.
but i can say one thing that they will find next to use to view it TOR
