Behavioral Control
You can run Linux, self-host everything, and de-Google your entire life — but if you still open Instagram 47 times a day on autopilot, you haven't fixed anything. This is the layer where PewDiePie coined the term "tech fencing", and it might be the most important one.
Based on: PewDiePie's "I Fixed YouTube!"
The Core Insight
Layers 1 and 2 are about what tools and services you use. Layer 3 is about how you use them. This distinction matters because you can have the most privacy-respecting setup in the world and still lose three hours to a YouTube rabbit hole you didn't choose.
PewDiePie realized something that sounds obvious but isn't: the problem isn't just that Big Tech collects your data. The problem is that these platforms are engineered to hijack your behavior. The infinite scroll, the autoplay, the algorithmically curated feed — these aren't features, they're traps. They're designed by teams of psychologists and data scientists to keep you engaged as long as possible.
"I catch myself opening apps without even thinking about it." — PewDiePie, "I Fixed YouTube!"
That quote is the whole ball game. The algorithm doesn't need to be smarter than you. It just needs to catch you in that 2-second window when you're on autopilot — when your thumb opens Twitter before your brain has a say. The solution? Make that 2-second window a 6-second window. That's enough time for your brain to catch up and ask: "Wait, do I actually want to do this?"
The Two Pillars
Every technique in Layer 3 comes back to two ideas. These are the foundation of tech fencing.
Friction
Add small, intentional delays between you and addictive content. Not enough to prevent you from accessing it — just enough to make the action conscious instead of automatic. A 5-second profile switch. A DNS blocker that shows a warning page. Removing app icons from your home screen. These tiny speed bumps break the autopilot loop.
The apps are designed for zero friction — tap, scroll, consume. Your job is to add friction back. Not a wall, just a speed bump.
Filtering
Remove the algorithm's power to choose what you see. Strip the YouTube homepage. Unfollow everyone on social media and rebuild with RSS feeds. Block entire categories of content at the DNS level. Replace curated feeds with chronological ones you control.
The algorithm shows you what keeps you engaged longest. You should decide what you see based on what you actually value — not what a machine learning model predicts will keep your eyeballs glued.
PewDiePie's Techniques
Here's exactly what PewDiePie set up on his own devices. All of these are things you can do today.
Second Phone Profile
PewDiePie set up a second user profile on his phone (GrapheneOS makes this easy, but stock Android supports it too). His "distracting" apps — YouTube, social media, etc. — live only on the second profile. Switching profiles takes 5-6 seconds. That's it. Five to six seconds of staring at a loading screen.
It sounds trivial, but those 5-6 seconds are enough to break the autopilot. Your brain goes from "thumb moved before I thought about it" to "I'm consciously choosing to switch profiles to open this app." Most of the time, you'll decide it's not worth it. That's the whole trick.
DNS Blockers
At the network level, PewDiePie blocks ads, trackers, and specific distracting domains using DNS filtering (Pi-Hole or similar). This means even if you try to open a blocked site, it simply doesn't resolve. You get a blank page instead of a dopamine hit. It's filtering at the infrastructure level — the most powerful kind because you can't easily bypass it in a moment of weakness.
Unhook Extension
The Unhook browser extension strips YouTube down to its bones. No recommended videos. No trending. No homepage feed. No comments (optional). No autoplay. You see a search bar and your subscriptions — that's it. YouTube becomes a tool you use intentionally instead of a slot machine you pull by accident.
RSS Feeds
Instead of subscribing to channels on YouTube (where the algorithm decides what to show you), PewDiePie switched to RSS feeds. Every YouTube channel has an RSS feed. Put them in an RSS reader like Miniflux, Feeder, or Newsboat and you get a chronological list of every video — no algorithm, no "recommended for you," no manipulation. You see what you subscribed to, in order, nothing more.
Unfollowing Everything
PewDiePie unfollowed everyone on social media platforms. Not unfriended — unfollowed. This nukes the feed. There's nothing to scroll. If you want to see what someone posted, you have to go to their profile intentionally. This is friction and filtering combined: the feed is empty (filtering), and checking someone requires deliberate action (friction).
The Algo Brain Problem
Here's why this matters beyond privacy. Every time you open an app and let the algorithm decide what you see, you're outsourcing a decision to a system that doesn't care about your wellbeing. It cares about engagement — which usually means outrage, anxiety, or content so perfectly tuned to your interests that you can't stop watching.
Over time, this rewires how you think. You stop choosing what to consume and start reacting to what's presented. You lose the muscle of deciding. PewDiePie noticed this when he caught himself opening apps automatically — his thumb would navigate to YouTube before his conscious mind had even formed an intention. That's not a personal failing. That's a multi-billion-dollar attention economy working exactly as designed.
Friction breaks this cycle. It re-inserts your conscious mind into the loop. A 5-second delay doesn't stop you from watching YouTube — it stops you from watching YouTube without deciding to.
Honest Downsides
Layer 3 sounds elegant. Living it is messier. Here's what actually sucks.
It Requires Constant Vigilance
Unlike Layers 1 and 2, which are "set it up once and it works," behavioral control is a daily practice. You'll find yourself disabling the Unhook extension "just this once." You'll switch to the distracting profile "real quick" and emerge 45 minutes later. The friction helps, but your brain is creative and will find workarounds. This is an ongoing battle, not a one-time fix.
You'll Miss Some Content
When you strip the algorithm and move to RSS, you'll miss things. The algorithm was actually good at surfacing new creators and content you didn't know you wanted. RSS gives you only what you explicitly subscribe to. You'll need to actively seek out new voices, ask for recommendations from actual humans, and accept that your content diet will be narrower (but more intentional).
Initial Setup Is Tedious
Unfollowing everyone on every platform. Finding RSS feeds for all your channels. Configuring DNS blockers. Setting up phone profiles. Installing and configuring extensions. The initial setup takes a solid afternoon, maybe a weekend. It's not hard — it's just tedious. And you'll probably need to tweak things for weeks after as you discover what works and what's too aggressive.
People Will Think You're Weird
"Why can't you just check Instagram?" "Why do you have a whole separate phone profile?" "Why is your YouTube blank?" Be prepared to explain yourself or just shrug it off. Most people haven't thought about their relationship with technology at this level, and your setup will seem extreme to them. It's fine. You're not doing this for them.
Build Your Fence
Start with one technique. The second phone profile or the Unhook extension are the biggest bang for your time.
Guide: Fix YouTube
Strip the algorithm from YouTube. Install Unhook, set up RSS feeds for your channels, and turn YouTube from a slot machine into a library.
Guide: Browsers & Extensions
Your browser is your window to the internet. Make sure that window has good blinds. Firefox, uBlock Origin, and the extensions that matter.
