I’m a member of Facebook.
I own some shares of a certain stock. I have never once used Facebook to do any kind of research on the issuing company, nor have I stored on my Outlook application any data whatsoever regarding this stock. I have, however, mentioned the issuing company once here at the SDMB years ago.
Facebook is sending me notifications that some Facebook members, strangers to me, are posting comments on its page dedicated to this stock’s issuing company. I have not followed up on these notifications to visit the page in question. But I’m still getting notifications, and it’s pissing me off.
The only answer is that Facebook is snooping on my browsing habits, which unnerves me.
Now that I’m typing this, I’m remembering that years ago Facebook sent me one of those “you may know this person”, and gave me a name I didn’t recognize. However, somehow I worked it out that she was a moderator here at SDMB. I never once visited any Facebook page dedicated to the Straight Dope. There was no way that Facebook could know I was a Doper without looking at my browsing habits. That was another incidence of snooping which is not sitting well, especially nowadays with scary virus infecting our technology.
