How so, if my adblocker prevents loading the add?

The site itself I am visiting could do so and share it with FB and whoever, sure - but this would be a different scenario.

Do you know if the social media icons that people put in their email signature can also be used to collect data on sender and recipient? I tried searching for information on this a while back but all I got in the search results were tutorials on how to add the social media icons in the email signature 'block'. :/

"Tracking" is a bit different, if I go to a big news site, that happens to also serve FB ads - than going to FB directly and complain that they track what I do at their place.

And like I said, if I use a adblocker preventing to load FBs add in the first place, then how can they meaningfully track me in any way?
