> suddenly Facebook's computer started calling me and my friends by name

Here's one creepy correlation horror story...

I just started at a new job, so got a new email account in a new domain that I've never been associated with before.

Last week I got an ipad as a gift, set it up with my personal account on my personal domain.

Last few days, I start getting spam from apple on my work email about service offers for this new personal tablet!!

Zero relationship between the accounts or domains!

The only possible explanation is they're correlating the IP address and going by that. Very creepy.

I stopped using Facebook when I was looking around the HTML tags for an image (can't recall why) and noticed it listed keywords for the image. The keywords were lacking context and only mentioned objects and weather, so it was obvious the user didn't assign them. Facebook logging what's in photos is creepy enough, but the fact it was happening in the background was the worst.

Those are alt tags and useful information for people with low vision who use screen readers
