I'd like to block just 4 specific websites but AFAICT there is no such option.
There's the option to "Limit Adult Content" but sadly it blocks way too much. For example it blocks stackexchange.com. I searched for restaurants on Google it blocked every single result. There's the option to only allow a whitelist of sites but that's not useful for me either. I'd have to add every result and every link I click on.
Effectively I'm looking for a blacklist option. Is there a way to do it? Maybe install a custom network profile or something?
Well so profiles don't solve it. They just do the enable the same features as available from the settings.
Next thing is to look for passthru VPN software or something like that
