Re: welp....
Sorry, but do you seriously rely on the sufficiently "technically inclined" to "starve the beast"?
Out of the many millions of people using the Internet, how many are capable (and willing!) to build and maintain a DIY filter on their home networks? Not everyone using a browser is a seasoned network admin.
Besides, installing and maintaining a filtering Pi on all their friends' and relatives' homes might become a full time job for the 1% who can actually do it... IMHO some will do it, most won't, at least not for long.
