does anyone know of a way to accurately pinpoint my joining date? the closest I can get is 4 years and 273 days ago when looking at my friends list, but I'm very sure I joined earlier because I introduced the person I used to pinpoint my current joining date to the server.
There is a method to check your join date via the Potterworld API, however your join date was set as "-1", which means your join date was not tracked at the time. (This period was 2014 - early 2016).
