Since the dawn of the internet, online ads have been a plague to many internet users and a godsend to advertisers. With the evolution of online ad industry changing dramatically over the years from serving flashing banners to popup videos, many users have become discontent with advertising networks and started to fight back against these unethical ads with ad blockers, such as the Ad Nauseam Chrome extension.

Recently, Google announced that they were introducing a built-in ad blocker into Google Chrome to start blocking ads that disregard privacy and facilitate bulk surveillance agendas. For many networks that are part of the Coalition For Better Ads, this new update did not affect how their ads are displayed. But for less ethical networks, it's removed most of their hidden ads almost overnight. You might think removing all of the unethical ads is a good thing, but for some users, that’s not enough.

Some people want total online anonymity, which means no tracking, no remarketing, and no ads, no matter how regulated they are. Although most ad networks give you the option to turn off tracking, some users don’t trust them and have decided to take their privacy into their own hands.

A plugin that has gained popularity in recent years for messing with advertisers tracking on your behalf is Ad Nauseam. This plugin works in browsers such as Firefox and Chrome by clicking all the ads on a website to confuse the advertising networks and “protect your online privacy.”

It might sound like Ad Nauseam is doing everyone a favour by protecting their privacy, but is it really just contributing to ad fraud and costing advertisers millions? Here’s what you need to know about this controversial plugin.

What is the Ad Nauseam extension?

Like we briefly touched on above, Ad Nausem is a browser extension that silently clicks ads on behalf of the user. Initially released for browsers such as Google Chrome and Firefox, the extension has caused quite a stir in recent years. Here's their official promotional video for the plugin below.

The creators behind the plugin state they protect users. Ad Nauseam clicks on every ad it sees, which helps hide your online tracks, giving you increased online privacy. The theory behind the plugin is that to stop tracking by advertising networks, it regularly clicks on every advert to confuse the tracking cookies stored on your computer. By clicking enough times on ads, all the data profile the advertising network receives is useless and unusable. Although the video states "lets work together to an honest and meaningful do not track standard" is clicking everyone's ads really a good way to achieve this?

So far it’s been deemed a massive success by its creators, but not everyone is happy about it.

As of today, Ad Nauseam is no longer officially listed on the Chrome web store due to it being removed back in 2017. If it's meant to be helping users protect their online privacy, why was it removed in the first place?

Why was Ad Nauseam removed from Chrome?

Every month, thousands of Chrome plugins are removed from the Chrome store due to them not meeting strict guidelines set by Google.
The reason Google removed the Ad Nauseam extension from their store is that they viewed it as malware instead of an actual plugin. To protect users, Google automatically disabled it for thousands of people who had it installed, amplifying users' discontent.

Coming out and saying a plugin is malware is a bold claim, especially when they didn't release much evidence alongside their decision. But after all, Google is the judge, jury, and executioner so whatever they decide goes!
So why exactly did Google view the plugin as malware? Was there something hiding within it that the creators weren’t telling anyone about? Well, it’s removal could be down to a number of reasons.

First of all, the extension does a series of automated clicks on behalf of the user without telling them exactly what it's doing. To Google, this probably sounds suspicious. If it clicks things for users without them knowing exactly what it's clicking, then Google isn't going to be too happy with that - and it explicitly goes against the Chrome Web Store terms of service (and they're also not going to be too happy with their advertiser's dollars being wasted with no ad revenue!).

There have been many examples of Google removing plenty of suspicious plugins, but one has to wonder if Ad Nauseam was indeed removed for suspicious activity or simply because Google didn't like it clicking ads all day. It's worth noting that Ad Nauseam is, in fact, an open-source project, so anyone can check the code for malicious activity themselves if you're technically inclined.

The most likely reason why Google could have removed the plugin is that Google wants to protect their ads and advertisers as much as possible. If you didn’t know already, Google owns the largest online ad network in the world, Google Ads, which currently has over 3 million 3rd party publishers in its network.

With so many websites using the AdSense program to display ads on their site, there’s a near-certain chance that Ad Nauseam is clicking Google’s own ads and costing them money - and the search engine giant won't like that.

Since Google’s ads run on a pay per click basis, every click an advert receives, the advertisers will be charged for it regardless if they end up buying or not. Considering Google makes most of their money from the Google Ads platform, it’s crucial they maintain a high level of quality traffic, or else advertisers will go elsewhere.

Knowing that Ad Nauseam clicks on every ad it sees regardless of if its Google’s ads or not could be a reason why Google removed it. If a million people had the extension installed, then they could be losing millions of dollars a day due to these fake clicks. By removing the extension from the Google store, they’ve probably saved themselves a lot of lost revenue. Of course, the morality of that decision is a discussion for another time (Do Google have the final say in their own "Walled Garden"? Is Ad Nauseam simply an expression of freedom of speech? There's a ton of debate to be had here.

Although the plugin has been removed from the store for over 500 days, it is still actually possible to manually install the plugin. This means that despite Google’s best efforts to kill the plugin, there are still plenty of users actively using it although the numbers are unknown. Installing unverified plugins comes with its own issues such as having to manually update it every time there is a new version. It's worth noting that the plugin is still available on the Firefox browser.

Ad Nauseam vs. uBlock Origin

Now you know why Ad Nauseam was removed from the Chrome web store, how does Ad Nauseam compare to other ad blockers such as uBlock Origin?

Well for starters, Ad Nauseam is actually built on top of the uBlock Origin plugin and uses its foundations to detect the ads on a page. For those that don’t know, uBlock Origin is a super popular ad-blocking browser extension that currently has over 10,000,000 installs as of writing.

Yet compared to Ad Nauseam, uBlock only blocks ads on websites and doesn’t actually click them. The clicking aspect is what Ad Nauseam introduced with its plugin and is currently the only one out there that we’re aware of.

Due to uBlock still being available in the Chrome web store, it's clear that more people use it. Not only does it do exactly what it says it does (block ads) but it’s also been verified by several reputable sites and browsers unlike other ad blockers. Having said that, with the looming introduction of Google's own in-browser adblocker, who knows how long it is until plugins like uBlock are also in the firing line.

So which is better? Well, that's a moral question for you to decide.

Don't want to lose money? Don’t let Ad Nauseam click your ads

Regardless of your views on the morality of such a plugin, it's only fair that advertisers have the option to limit their exposure to such plugins if they choose to do so.

If you run ads on Google display network, then you could be at risk of having your PPC ads clicked by the Ad Nauseam plugin. With thousands of people still using the plugin on Chrome and Firefox, almost anyone is it at risk of having their ads fraudulently clicked.
