Why a Porn Block-List Never Works (and What to Use Instead)
Quick answer
A porn block-list never works because there are far too many adult sites to enumerate, new ones appear every day, and blocked sites reappear instantly under new addresses. Category filtering solves this by blocking content by type rather than by name, so it catches sites that were never on any list — including ones created minutes ago.
Why we won’t hand you a list of sites
Two honest reasons. First, publishing a directory of adult sites would be pointing people toward the exact content this tool exists to block. Second, even if we did, it would be obsolete before you finished reading it — which is the whole point below. A list is the wrong tool, not a missing one.
So instead of a list, this page gives you the thing a list is a poor substitute for: a filter that doesn’t need to know a site’s name to block it.
The four reasons a block-list always loses
Short answer
A manual list fails on scale, speed, evasion, and upkeep. There are too many sites to name, new ones launch constantly, blocked ones return under fresh addresses, and you'd have to maintain the list on every device forever. Any one of these breaks it; together they make it hopeless.
- Scale.
The number of adult sites runs into the millions. No list a person builds, or copies, comes close to covering them.
- Speed.
New domains appear every single day. A list is a snapshot; the problem is a moving target.
- Evasion.
Block one address and the same content reappears under a mirror or proxy domain within minutes. The list is always one step behind.
- Upkeep.
Even a good list has to be maintained on every phone, tablet, and computer, indefinitely. Miss a week and the gaps open back up.
What works instead: category filtering
Quick answer
Category filtering blocks content by what it is, not by its address. The filter classifies a site as adult, scam, or malicious and blocks the whole category — so a brand-new site is caught the first time anyone visits it, without being added to anything by hand.
This flips the maths in your favour. A list makes you responsible for naming every bad site before it can be blocked. Category filtering makes that unnecessary: the filter recognises the category and stops the site on sight, whether it launched last year or ten minutes ago. There’s nothing to maintain, because there’s no list to keep current.
How category filtering works in practice
Kahf Guard’s Safe Internet Protection runs this at the DNS level. Every site your phone opens first asks for an address; Kahf Guard answers through a filtering resolver that classifies the request and refuses to resolve adult, scam, and malicious categories. Because it happens at the network layer, it covers every app and browser at once, and it catches unlisted sites automatically. You choose Strong or Moderate, and the filter does the naming for you.
Set it up in two minutes
- Install Kahf Guard.
Download it from the Google Play Store or App Store.
- Turn on Safe Internet Protection.
Choose Strong or Moderate. Category filtering starts immediately — no list to import.
- Add your own sites (optional) and lock it.
Use the Website Blocker for any specific sites, then enable uninstall and DNS-change protection so the filter holds.

Common questions
Where can I get a list of porn sites to block?
We don't publish one, because any list is obsolete immediately and can't cover the millions of sites that exist. Category filtering blocks adult content by classification, so it works without a list and catches new sites automatically.
Why doesn't a block-list work?
New adult domains appear faster than any list updates, blocked sites reappear under fresh addresses within minutes, and you would have to maintain the list on every device forever. It fails on scale, speed, evasion, and upkeep.
What is category filtering?
Instead of naming sites, the filter classifies content by type — adult, scam, malicious — and blocks the whole category. That catches sites that aren't on any list, including brand-new ones.
Can I still block specific sites I choose?
Yes. On top of category filtering, a Website Blocker lets you add particular sites you want blocked, permanently or on a schedule. It's the right tool for a handful of named sites.
Does category filtering block new porn sites automatically?
Yes. Because it blocks by classification rather than by address, a new site is caught on sight without being added to any list.
Is category filtering better than a hosts file?
For adult content, yes. A hosts file is just another manual list with the same problems, while category filtering doesn't depend on enumerating an ever-changing set of domains.
Skip the list, filter the category
Block adult content by what it is, across every app — no list to build, no list to maintain.
