Como bloquear facebook, batepapo MSN Messenger, rede social Orkut e sites impróprios?

Hi. First of all, tnx for the web filter program. It's a very good software.
The project is still alive?
And ...... sorry for my question ....... but how can you keep alive a free project (and a website) without banners, donations, or something else?
I'm using the kurupira web filter from only one day and I think that it's very complete and useful. I think there is much work behind!

Actually, the project is not fully operational yet. We are bearing the costs by ourselves. If the Project reach the point of profitability we will set in motion the social aspect of the project.

All clear. Thanks for your work
