No they’re not. I just had to stamp on that. They are absolutely categorically not 99.8% accurate. I worked in an industry that used them, or rather, given how sensitive they are, was given ‘restricted access’ to said algorithms, I think you’re thinking of something else. Because even those ones are most definitely not 99.8% accurate, and they most certainly are not accessible to John Q Public and their website to generate clicks, but are instead designed for legal authorities, governmental intelligence agencies, and the banking sector, under restricted license (Which is what I worked in) .
Ironically, one of the things you would -not- be able to tell from such information, is subscription to video games.
You can tell a lot. You can tell if someone has been asking naughty questions.
Naughty questions about how to best dispose of a body, you can tell if someone has been looking up algorithm’s for code cracking, where to buy tasers, unlicensed vehicles, Dvd’s of a ‘certain’ nature. You can find stuff on there that would make your blood boil and your fists clench in anger. It’s not available to the general public, or some monkeys on the internet.
Anybody who makes a claim that they have complete access to such information, outside of being a member of said organisation, is essentially.
A Liar.
Also, how do you clock these things working? You don’t say 99.8%…Who uses that? That is how I know you are chatting utter whiff. Who says that? Nobody says that. You only use percentages in certain industries. A Gaming website claiming to have confidential information? I don’t think so.
99.8%…crazy, man, what will they think of next, that is like the guy who said that 96.4% of Blizzard Devs were Horde…
99.8% is close enough, that I nearly would go to town on someone claiming 100% and utterly destroying them…
