it from another page I thought). The idea behind this script is good: Fetch a
porn link site, filter out all links and you will get a blacklist.

which filters every night new porn domains, over 9500 til now.

blocked pages. Check them and enter them to a second list, a whitelist.

Peoples (and even pupils) learn fast - sometimes. If they find anonymizer /
redirecter, why not blocking them too? (Who needs those?)
