Tracking
This is the answer. Look up the Facebook Pixel and Like Button. Putting them on a site lets Meta track your activity across the web, even when you’re logged out or don’t have an account. I’m sure Twitter, Reddit, et al. are doing the same by now.
Im pretty sure a lot of these tracking widgets are invisible/zero size/offscreen too, so its not just a 'click here to share' button but purely a User_ID36ax48dd99y42s52l840a2648 visited this site at 15:37:23 on 20250405 and looked at X.
