The rules say we should default to assuming good faith in comments. But it's hard when I see this comment in 2026.

what would the bad faith motive even be?

$$$, one of the classic bad faith motives. Most of tech nowadays is subsidized by advertising and profiling to some degree, often quite a large degree.

The claims made on the website linked here are plain wrong. The person behind them is subject to an account restriction for scraping and other violations of LinkedIn’s Terms of Service. To protect the privacy of our members, their data, and to ensure site stability, we do look for extensions that scrape data without members’ consent or otherwise violate LinkedIn’s Terms of Service.

I look forward for you to post a rationale for the site reliably for these 6,000 extensions.

Not clear why it needs to scan for Amazon image downloaders, Rufus conversation extracters, Amazon delivery scheduler, Product Scanner, or pharmacy operations.

That was a two minute search here:

This entire response is full of lies. Having done a cursory search of the extensions, you do target ones that are based on religious affiliation regardless of the DOM actions they take.

Your comment is disingenuous, insulting and has only served to make me check more extensions and only browse LinkedIn in a secure, private window.

Have you (or anyone reading this) been able to "beat" fingerprint.com without Tor or turning JavaScript off outright? I've tried it various times over the last couple years, using different browsers with various privacy settings enabled and a VPN. I can get good partial results and am able to reset my fingerprint by changing my OS and browser at the same time, so it's not entirely there with regards to sniffing the h…

It is depressing how robust it is! I can beat it, but only be changing my IP. Since I'm not using a shared IP like a university/company might, my IP is giving them a lot of bits about me since I'm the only entity using it... No matter the browser switch, if I hit it from the same IP, it correctly assumes that my IP is still me. But the moment I switch to a different browser and change IPs I get a new fingerprint. Hav…

Fingerprint (and its ilk) use a tiered identification system to identify you, with a decrease in confidence with each step down.

They start with a supercookie approach (first-party cookies, third party cookies, indexdb, localstorage, session storage, favicon timing, etc) which is a direct look up, and unique. This is tier-1.

Next they slam as many signals as they can get your browser and network to cough up into an ML db and find your nearest neighbor. If its greater than threshold ${x} - they return its ID with a confidenc of say 85%

If that misses, they slide down to tier 3 which is your IP address plus some browser signals on a TTL so they don't just call everyone with your IP address "you". This is maybe say 50% confident.

Below that, they create a new record.

If you want to beat it - tbh - Safari, especially on IOS is a monster. Most people with an iPhone default to it, and they remove their biggest entropy signals (offlineAudio, canvas profiling), so they're left with almost nothing to work with that is really unique.

Fingerprint _really_ pushes merchants to reverse proxy their services so that they can serve cookies as first party and Apple doesn't nuke them after 1 week. Its complicated and most merchants don't want to diddle with it - but it circumvents adblockers (ps - use an adblocker and call out fingerprint specifically if you want to hit them. LLM to see who else you need to include).

After that, if you're on Apple, use their Apple-VPN service (forget what its called) - which exists _literally_ for this.

Oh ISPs are definitely collecting your browsing habits, and selling them to the highest bidder. It's one of the major reasons why I use a vpn.

Well what makes you think the VPN providers are not tracking? You would have to either self-host your own VPN server somewhere (maybe on a public cloud provider) or if you are truly paranoid, use something like Tor.

They have been subject to warrant requests, and had nothing to turn over. There are only a few vpn providers that I genuinely trust. (Mullvad, airvpn, etc)

Really though, I am not worried about 3 letter agencies performing legitimate law enforcement duties. I am worried about corporations hovering up more data about me than I'd want to reveal, and either using that as a basis to charge me more, or worse, they get hacked, and that data is used by bad actors to target me.

All illegal or unethical means can be explained, but not justified, by their ends. I'm quite sure having unfettered insight into the browser environments of your users makes enforcing your Terms of Service much easier, but held against the (even minute) risk of exposing one of users' political, religious or sexual preferences, any of which might carry with it massive risk of bodily injury or death in many parts of th…

Why is scraping even an issue? If people don't want others to find this info, just don't put it out there in the public?

The world isn't binary. People want to look for jobs and network.

At the same time they don't want their data turned over and sold to the kind of people who scrape LinkedIn.

Plus - Your data is LinkedIn's cash cow. They're not going to leave it out for every Tom, Dick, and Harry to export en masse whenever they want.

Javascript can query chrome extensions [1] and much more [2]. [1] - https://browserleaks.com/chrome [2] - https://browserleaks.com/javascript

This blows my mind. What good reason is there for giving javascript such permissions by default? This should at the minimum trigger an explicit permission request from the user.

My guess would be that the internet is run by developers. Apps will want this data so javascript provides it to make decisions about window sizing and user agent capabilities. Authorization would probably only occur if javascript was gated by non developers just as SSDP open and forwards ports on routers without user intervention or knowledge rather than an API that prompt the user. Just a guess.
