We once ran a trial at work for a lead generation software.
It could show who visited your website, what company they worked for, how to contact them, their socials and even a video of exactly where they pointed and clicked their mouse.
No sign up required, all by fingerprinting.
Shit was creepy as fuck, glad we don't use it anymore.
It also made me realize fingerprinting is almost impossible to avoid. There's so many little things gathered to identify you, it seems unavoidable to be traced.
