Indeed - I have one because of having a Youtube channel. I have several google accounts thinking about it. I have a gmail account from years ago and that creates a google account. And to upload videos to youtube you need a google account.

I don't huge terrors about the HUGE amounts of data that people hold on me. But I find it interesting. The thing that made me look at things again was this book - How to Survive the Internet. A friend of a friend wrote it and my friend lent it to me last week and I found it interesting enough to get my own copy.

It was a good time to do an audit of 20+ years of internet usage and make some changes. It's a very good book and is available as a Kindle book too.

I download my facebook data various times in the past. But it is only a tiny subset of what they have access to. For example, they have the information of where you go to Facebook from. That information is not contained in the downloadable information form Facebook.

From websites I have I know exactly where people come from. It is just standard stuff.
