it will identify you in a group of a few thousands other people.. google said the cohorts should not be too big. the main problem with floc in my opnion is that it extend tracking to sites where no tracking happened before. today to track they need you to go to a site that has an ad or a "social media" button. basically something that make you access their server while telling the site you came from, maybe set some cookie while there so they will know you are you when you access some other site.. if a site does not have any ads or does not have social media buttons they cannot track you there.. the same if you enable adblocking.. now with floc it will use every site you accessed in the last week to calculate your floc.. so they will know what sites you are visiting even if those sites does not have anything that would allow you to be tracked today or if you use adblocker and stop them from tracking by other means..
