What Happened?

A few days ago, I used a photo of one of my close friends in one my previous post but I did not mention his name in it.

I also shared the post on a Facebook group that he was not part of, and I did not mention his name in at all.

His picture and story wasn't the main part of my post, it was just a funny story I mentioned in passing. I did not have the intention of him finding out about the post at all - not that I was trying to keep it a secret, I just thought it was irrelevant.

A few days later..

This friend of mine contacted me, asking me about the story I shared of him in the post. He told me that Facebook shared the post on his wall. This freaked/amazed me because:

1. Why did Facebook share the post on his wall when I did not mention his name at all? The only way Facebook would have recognized him is through some facial recognition of his face in the thumbnail?
2. Why did Facebook share a post that was posted in a group my friend was not part of at all on his wall?
3. I did not know my post was being shared specifically to his wall. So what else of mine is Facebook sharing specifically to someone without my knowledge of?

What would surprise me even more is if Steemit is somehow sharing our data with Facebook? Why would Steemit do that unless, Facebook has a stake in Steemit? Or Facebook is also data mining the Steem blockchain? Or Steemit is sharing our data with 3rd party sites for profit? I love technology, but I can't pretend to imagine understand how any of the technologies involved in my assumptions work.

Vindication for my Friend

I apologized to my friend for talking about him without informing him. He didn't mind, but he wanted me to share his version of the story because he thinks the way I wrote it makes him sound like a creep, but he sees his special power as more elegant than creepy. Here is his version of the story:

I feel violated.

This is the truth.

We were doing interviews and people were making noise outside so I went outside to see what the noise is all about.

People were arguing over a fancy pen. Whose pen is it? Are they coming back to get it? Etc etc.

Later I came out of the interview and everyone said "how did you know it was her pen?"

I said "You can tell from the unique musky scent."

That is the truth. Your story makes me sound like a creep.

I sniffed the pen and said "It's [name]'s pen."

In all seriousness though, could someone clarify or answer these questions for me please? I would really like to know where the things I post are reaching without my knowledge and how.

Or it could be my friend is just bullshitting me, he has an account on Steemit and somehow just came across the post but told me he doesn't.
