Loudly

Good morning!!

I have a doubt. I have been finding out on the filters that settle in the computer so that my son could not enter certain contents online. I have seen some like this one: http://www.comunica-web.com/verarticulo-filtro-proteccion-menores-internet_139.php
started by the Commission of Innovation of the Meeting of Andalusia (Spain). I would like knowing if someone has this installed for his children, and of being like that, if really they work or if they know someone that should be trustworthy. Thanks.

A greeting.
