I have been thinking a bit about home router/squid solutions - with three kids now, I want to allow the free exploration of the sum of all human knowledge, but boy there is a lot of crap out there.

So, DNS based blocking is both slow to react and needs constant vigilance. I think there are some open sourced DNS blacklists

Secondly, I'm confused by YouTube - I value the idea of interview with rosa parks, but it's then three clicks to any amount of violent over-sexualised rubbish.

I am interested in Adblock on a router - but mostly I am trying to prevent the "rubbish" getting through.

So I think there are few solutions beyond "turn off internet access unless I am sitting with you"
