I think those who use cheats are mostly school age kids who do it to troll people or to boost their self-esteem.

If 99% have the account then rejecting the 1% seems like a good way to not let different weirdos (like me) enter the country?

And the irony is that this would reject only those who properly did the paperwork and won't stop the people who prefer different methods of entry.

Yes "PPA" is absolutely shady, it is a browser cooperating with ad companies behind user's back. I do not understand why I need this on my computer.

It is noteworthy that there are browsers that resist fingerprinting much better than Chrome or Firefox. But these browsers are made not by a reputable companies but by shady Russian hackers, they are called "anti-detect browsers". Their purpose is to allow using multiple social network accounts from one machine and avoid getting banned for this.

There is a way - provide random garbage via browser APIs, for example, fake GPU name, fake core count, fake IP addresses for WebRTC. But browser vendors do not want to do it. You have to compile your own browser.

Such browsers that allow you to masquerade as a different browser do exist but they are targeted at people doing social network marketing (spam and scam) from multiple accounts. Because social networks do not allow using multiple accounts from the same device. These browsers are called "anti-detect browsers" and you can find info about them on Russian underground forums.
