As usual AOU is technically correct but has the bedside manner of a jackass. I will potentially waste my time but I will attempt to explain ... - Poal.co has to set a cookie to track your session so that basic login functionality can work. - Websites can attempt to read any cookie on your system, even cookies from other sites. These are known as third-party cookies - There are lots of advertising companies that install their own cookies to track you. They sell a service where a website owner can read the third-party tracking cookies on a user's browser and then look up info about the user from the marketing company data base. Because of this there are apps like uMatrix that monitor cookie use and access. **What you are seeing is not Poal.co tracking you but rather the gab.com website reading your Poal.co cookie as a method to identify Poal.co users.**
