I had a rather "eye opening" experience with a Facebook bot account just now. I'll admit, I've always wondered if it's either social media bot farms being allowed to operate openly on these platforms or the platforms themselves. I did not 100% know which was the case until now.
The bot states "I see in your profile that you supported the truckers insurrection" and then says I'm racist lol.
But here's the thing, I even went through to double check, I do NOT have a single post up on my PUBLIC feed of the Canadian freedom protests. None.
It's only in my friends only view.
I've read somewhere that FB cookies effectively monitor all your browser's activities which is how they can keep advertisers up to date on what to show on your feed. Perhaps they tracked your comments and viewership of this site?
