Overview
This page describes some ways to block bad sites.
One frequently requested feature is to block bad sites but allow images on ordinary sites. A little thought will reveal that such a simple request is actually fairly difficult to do without blocking some “good” sites or allowing some “bad” sites. If mostly is fine with you, then read on.
Those who want to allow images in general should read how to allow images by default.
Option 1: Use a DNS filtering provider and lock DNS settings
See how to enforce a dns filtering service for details.
Option 2a: Use flee words and/or flee hosts.
For example, to block all pages that contain the word “pizza”:
pluck + flee word pizza
See flee for more information.
You can also try using a large flee host list.
Option 2b: Use blot words
Like flee, but only acts upon visual content rather than the entire page.
pluck + blot word pizza
Your local pizzeria’s website will be completely blocked if using a flee rule, but if using a blot rule, you will still be able to view the site in text-only form.
Option 3: Use one of Plucky’s safe features
For example:
pluck + safe
pluck + nofirefox
These are much less effective on Android than on desktop – Android users should primarily use either Option 1 or 2. See safe for more information.
Mix and match
You can use all of the options above at once if you like.
