I cannot remember the name of it, but I definitely read a post somewhere about a company X that does this as a service. In short, company A who you have an existing account with shares your info with X, who saves it to a cookie. Company B which you visited does the same. Both of them can ask X for info about a site visitor by virtue of the sharing policy... I find the idea pretty disgusting.

You're right. Ugh I can't remember either, but I vaguely remember learning about it on Hacker News. It was nothing technically illegal or anything malicious, it was just normal web-cookie tracking in overdrive. Then the company whose page you hit pays the tracking company for the information. There have been universities that looked into it for their admissions pages, but decided against it.
