Poison Your Metadata

They're going to collect your data anyway. Here's how to make it useless.

There is a strategy as old as warfare called chaff. During World War II, bomber crews would dump bundles of aluminum foil pieces out the plane door before flying over enemy territory. They were scattered across the radar screen as thousands of fake signals. The real plane was still there and the radar was still working. But the data was garbage, and that was the whole point.

You can do the same thing to your data.

The standard privacy advice more or less goes like this: use a VPN, block trackers, delete your cookies, opt out where you can. Go dark. That advice isn't wrong. But it assumes you can actually disappear, and you can't. Every website you visit, every search you run, every ad you ignore and scroll past, is data. It flows to Google, Meta, your ISP, and a dozen companies you've never heard of.
You're not going to stop that from happening, but you can feed them garbage, and they will gladly eat it.

Researchers Finn Brunton and Helen Nissenbaum wrote a whole book about it, published by MIT Press in 2015, called Obfuscation: A User's Guide for Privacy and Protest. The argument is simple: instead of trying to hide from surveillance, flood it with noise. Nissenbaum didn't just theorize about this. She built tools to do it.

AdNauseam is the most aggressive of the bunch. It works like a standard ad blocker in that it hides ads from you. But unlike uBlock Origin or Adblock Plus, it doesn't just block them silently. It clicks every single one. Every blocked ad is clicked in the background. Without you actually noticing it.

To the ad network, for example, you might look like someone who is simultaneously interested in luxury watches, baby formula, cryptocurrency, knee surgery, vegan diet options and smoking brisket. Google banned it from the Chrome Web Store in January 2017. The reason is obvious. AdNauseam runs directly against the core of Google's business model, serving you ads, and Google controls what goes in the Chrome Web Store.

After the ban, Google treated the extension as malware to stop users from installing it manually through developer mode. AdNauseam still works. You just can't get it from the Chrome Web Store. It's available for Firefox and Opera through the normal extension stores, and you can install it manually in Chrome using a file from the GitHub page.

TrackMeNot targets search instead of ads. It runs quietly in the background and fires fake search queries at Google, Bing, Yahoo, and others. Not random words, but search queries that evolve over time, by pulling related terms from real search results, making the whole thing look like genuine human behavior.

The idea is that your real searches get buried in a cloud of decoys. The search engine sees an incredibly active user with impossibly diverse interests. TrackMeNot was built by the same core team behind AdNauseam. Google banned it too, using the same malware label, according to the TrackMeNot team, the day after promising a two-week grace period to address concerns.

However, TrackMeNot hasn't been updated since November 2019. It still runs on Firefox and you can still install it manually on Chrome-based browsers. But unmaintained extensions carry security risks.

Noiszy takes a different angle. Instead of poisoning your search or click data, it poisons your browsing history. It opens a background tab and quietly navigates around a list of news sites you approve, clicking links, reading pages, moving around like a human would.

Your ISP, your browser, the analytics scripts embedded in those sites all see traffic that isn't you.

Noiszy was built in 2017 specifically in response to the US Congress voting to let ISPs sell your browsing data without consent. The creator had a direct and practical motivation: if they're going to sell your data, make sure it's useless.

Go Rando is the social media version, aimed specifically at Facebook. Every time you click Like on anything, Go Rando intercepts the click and randomly picks one of Facebook's six reaction options instead. Happy, sad, angry, haha, wow, love, all distributed randomly across everything you react to.

Over time, Facebook's emotional profile of you becomes flat. You appear to feel equally about everything. The sentiment data, which feeds into ad targeting, news feed ranking, and potentially government profiling, becomes useless.

It was created by artist and researcher Ben Grosser, who put it plainly: Facebook is not a neutral facilitator of communication. It is a machine optimizing for engagement, and your emotions are the input.

None of these tools are perfect.

TrackMeNot can trigger CAPTCHAs if you set the query rate too high. Go Rando may have compatibility issues with Facebook's current interface, since Facebook updates its code constantly and the extension is no longer actively maintained. Noiszy's update history is thin.

And there's a real ethical question. Small, independent publishers survive on ad revenue. The target is big-tech, like Google and Meta. The collateral damage might be the blogger or the independent local news outlet. That's a real cost. It is worth noting that independent publishing existed before Google's ad network did, and will exist after.

If the obfuscation tools above feel too aggressive or too maintenance-heavy, there are quieter options worth running alongside them.
uBlock Origin is the ad and tracker blocker that AdNauseam itself is built on, and remains the most solid foundation for any privacy setup.

Privacy Badger, built by the Electronic Frontier Foundation, learns as you browse and automatically blocks trackers that follow you across multiple sites.

Decentraleyes takes a different angle entirely: instead of blocking requests to large content delivery networks like Google Hosted Libraries, it intercepts them and serves the files locally from your own browser. The result is that Google never sees the request in the first place. None of these three tools poison your data the way AdNauseam or TrackMeNot do, but they quietly cut off a significant amount of the collection before it even starts. They complement each other, and all three run without you having to think about them.

The companies know this is happening. Google employs hundreds of people specifically to detect ad fraud. They use machine learning, behavioral analysis, and pattern recognition to filter invalid clicks. They are very good at it. In 2021, researchers ran an experiment using AdNauseam against Google's own ad platform. Google mailed them a check for $100, and they didn't cash it.

The argument for doing this isn't that it will bring down the surveillance economy. It won't. It's the same argument WWII pilots had for throwing chaff out the window. You're still flying through radar. The enemy is still there. But now the screen is full of garbage, and you've made your data a little harder to weaponize against you.

Before anything else, check myaccount.google.com/data-and-privacy under Ad personalization. See what Google already thinks of you. Then run these tools for a month and look again.
