I just added a list of websites to the hosts file, but the thing is - I know how to unlock that stuff in a few seconds (and LeechBlock can be turned off even faster).
I wish I could lock websites between certain hours at the ISP level, and unlocking shouldn't be easy, and should take a few hours.
Do it at the router level and then reset the password to gibberish.
I still would like to visit the websites, when I don't need to work.
