Honestly, account or not, they are still able to track you in full. It doesn’t truly matter if you have an account. They track everyone with or without an account. So all I am saying is don’t make your life harder by deleting an account and thinking “Haha, I got one over on Facebook, they can’t track me now!” They can, and are, and have a full profile on you. GDPR fines are just the cost of business. They can afford it and make more off of the sale of data than they get fined. It’s a net positive.
