How to block porn
Blocking adult content on the devices you own, and making the block hold at the hour it stops feeling like a good idea.
How to block porn (and make it actually stick)Blocking porn is easy. Keeping it blocked at 1am, when you are the person holding the off switch, is the actual problem. Here is how to set it up so it holds.How to block porn on WindowsWindows gives you more room to enforce a block than any other platform, which means a Windows setup can be genuinely hard to get around. Here is how to use that.How to block porn on AndroidThe phone is where most of this happens, and it is the device people most often leave unprotected. Android gives a blocker enough room to do the job properly.How to block OnlyFansBlocking one domain is the easy part. The routes in are usually links from somewhere else, which is why domain blocking alone tends not to hold.
How to stop doomscrolling
Blocking the apps and sites that take the evening, and retraining the feeds on the ones you have decided to keep.
How to block social media on your own devicesSocial media is not a website problem, it is an app problem, a notification problem and a habit problem. Blocking it properly means covering all three.How to block Instagram on your phone and computerInstagram is the one most people underestimate, because each visit feels short. It is the number of visits that does the damage.How to block TikTok for goodTikTok is the most efficient attention machine ever built, and it is not a fair fight. Removing the option beats trying to use it moderately.How to block YouTube Shorts without losing YouTubeYouTube is genuinely useful. Shorts is a different product wearing the same logo, and it is the part that eats the evening.How to block RedditReddit is the one people defend hardest, usually while describing a four-hour session they did not plan.How to block Twitter / XThe site changed its name but not its effect on your afternoon. Blocking it means covering both domains and the app.How to retrain a feed that keeps showing you things you do not wantYou did not search for it, you did not follow it, and it keeps arriving anyway. Feeds learn from behaviour, and the behaviour they learn from is not the one you would choose.How to retrain the TikTok algorithmTikTok reads behaviour faster and more aggressively than anything else, which means it goes wrong quickly and can be corrected quickly.How to retrain the Instagram algorithmInstagram has two problems: Explore, which suggests things from strangers, and Reels, which does the same in video and much faster.How to retrain the Facebook algorithmFacebook has spent years increasing the proportion of your feed that comes from accounts you never chose. That is the thing to attack.How to retrain the YouTube algorithmYouTube is the one platform that genuinely hands you the levers. Recommendations run on watch history, and you can edit watch history.

What the tools do, what the words mean, and what the evidence actually says.
Porn blockers: how they work and what to look forMost porn blockers stop the sites they already know about and hand you an off switch. The useful ones do neither.Website blockers: what they do and where they fall shortA website blocker is easy to build and easy to defeat. The interesting engineering is entirely in the second part.App blockers: blocking the app, not just the websiteMost of what people lose their evenings to is now inside an app, where a website blocker cannot see it.Accountability apps: what they are, and whether you need oneThe accountability model is built on a simple bet: that you will not do it if somebody else will see. For a lot of people that bet pays off. For others it is the reason they never start.What digital accountability actually meansThe phrase has come to mean surveillance with a friendly name. It does not have to.How to stop doomscrollingNobody decides to spend ninety minutes reading bad news in bed. It happens because the decision was never made in the first place.How to quit porn: what the tools can and cannot doSoftware cannot do this for you. What it can do is remove the decision from the moment you are least able to make it, which turns out to be most of the battle.Porn addiction: what is actually established, and what is notThis is a genuinely contested area, and most of what is written about it online is far more confident than the evidence supports. Here is a more careful version.Blocking distractions: a productivity approach that survives a bad dayEvery productivity system works on a good day. The interesting question is what happens on a bad one.Does porn affect dopamine? A careful answerThis is the most confidently over-explained topic in the entire category. The honest version is more useful and considerably less dramatic.Does porn cause erectile dysfunction?This question deserves a careful answer rather than a confident one, because getting it wrong in either direction can lead somebody to ignore a genuine medical problem.How to find an accountability partnerThe hardest part is not the software. It is the ninety seconds where you say it out loud to somebody.Why motivation is not enoughYou were not short of motivation when you decided to stop. You were short of it at half past midnight, which is a different problem entirely.
For your situation
Platform and audience specifics, including the cases Kellet is not built for.
A porn blocker for Windows that actually holdsWindows gives software deep enough access to make a block genuinely difficult to get around. Most Windows blockers do not use it.A porn blocker for AndroidThe phone is the device that matters most and the one people most often leave open. Android gives a blocker enough room to do the job.Using a blocker as a coupleThere is a version of this that rebuilds trust and a version that quietly destroys it. The difference is entirely consent.A blocker for people doing this for faith reasonsMost tools aimed at this audience are built around confession to another person. That helps a great many people, and it is not the only honest way to do it.Parents: what this tool is, and what it is notYou have probably arrived here looking for a way to protect a child. This is not that tool, and it is more useful to say so than to sell you something that will disappoint you.A porn blocker adults choose for themselvesAlmost everything in this category is built for parents or for accountability groups. Very little of it is built for an adult who simply made a decision and wants it to stick.A website blocker for studentsStudy is the ideal case for blocking, because the distraction is mild, constant, and arrives precisely when the work gets difficult.A website blocker when you have ADHDIf the gap between intention and action is where things fall apart for you, a tool that tests your intention at the worst moment is the wrong tool.A website blocker for remote workIn an office, someone might walk past your screen. At home, nothing at all sits between a hard task and forty minutes elsewhere.
