Google has moved far away from "do no evil".
I feel like I'm always being watched - just to make some rich person richer.
I don't like ads, they're a menace to society, I will find something if I need it.

It's pretty easy to create a uuid. There are many ways to do it. Which is best for you would depend on how you're generating your website.
