hosts

ad and porn websites that I come across, that are not blocked by other famous hosts files.

the file safesearch forces google's (and potentially other search engines) safesearch.

other anti-porn hosts files:

StevenBlack

4skinSkywalker

add.sh

if you want to contribute, you can use add.sh to add your websites in:

./add.sh abc.com xyz.com ...
git push

or put the list of sites in a text file, one per line; then:

./add.sh list-of-sites.txt
git push

it automatically sorts the list and adds www variants as well.
