Thats irrelevant since I'm analyzing clicks from Google and Facebook and then looking at their movements via Fullstory. How does an adblocker alter that process?

It segments the audience. The people that are coming to your site aren't running adblocker, and might behave differently than those who do.

ublock origin has anti-tracker lists, and to use fullstory you add fs.js to the <head>. I could see it being blocked (like I just did in my custom list).
