What, in Liberia?IP addresses are PII pretty much everywhere in the civilized world, including the US. If you are doing what you say (and you aren't because your a liar), you'd be in violation of the law.
Are you part of a corrupt, penny-ante, piece of shit company that does this? Possibly. I can't deny it. Does any corrupt, penny-ante, piece of shit company have enough reach to effectively track consumers across domains? ... possibly porn? Possibly?
Yes. You are right on target there, sir. I'm a terrible person, and I work for terrible companies. You got me there. That was a real zinger. I'm surprised you didn't accuse me of intentionally spreading ebola from the hovel I use as a business address in Liberia.
But the reality of this situation is that your internet-lawyering has nothing to do with what companies do in the real world. And it has nothing to do with how real-world attorneys and law-enforcers think of this issue. PII laws are about what you do with the information, not whether or not you are allowed to collect it.
MR companies are not law enforcement agencies. We don't have to read you miranda before we take your data. Your browser gives us information if we ask nicely for it. And we use it to aggregate data, create statistical models that don't include PII, and that's what we share with our clients.
If you want to tell me that this is illegal, that's great and everything. You strike me as the kind of person who yells, "Free Speech! First Amendment!" every time someone on a privately-owned forum censors you. You don't seem to be able to tell the difference between what a government agency is allowed to do versus what a private owner is allowed to do.
Here's a hint, Captain Ridiculous: the two are not the same.
I'm not saying it's good or praiseworthy or that I like it. I'm saying that it's possible and that people do it.
