Log out, clear all cookies, get a new IP address (usually easy as unplugging your modem for an hour or so), and make new accounts. Better yet, don't make new accounts, and use platforms that don't require it -- or at least platforms whose accounts don't entail personalized advertising. Or, you know, look into individual platforms data and privacy options. Google, for instance, allows you access to some settings via https://myaccount.google.com/data-and-privacy https://myaccount.google.com/data-and-privacy; presumably particularly in a post-GDPR world, most of the big platforms have something similar. All depends how thorough you want to be. Reset a few advertising models, or basically join witsec.
