TLDR: Don't be creepy. I don't need to know who you are or pass that on to anyone else.
I store aggregate visitor numbers so I know how many people in total have visited a page.
I store visitors aggregate browser versions so I know what I need to support and what features I am safe to use.
Beyond that I don't need to know anything about anyone visiting my site. I have no way of identifying an individual user; because why would I need to do that, that's creepy.
I don't use any third party scripts or embeds on this site. Reporting information about people visiting your site to giant corporations is even creepier. I find it so strange that it is so normalised.
