I've never seen the point in going out with all guns blazing and burning your bridges. It might feel good to get it off your chest but you may as well just write it down on a piece of paper because hardly anyone will see it because in most cases it just gets moved to the mod room.
It's just an exercise in futility, your intended audience won't get to read it, but it will forever be in the mod room to be re-read and discussed when you get caught sneaking back, and everyone comes back. It might be a week or a month or even longer but they all come back. Proof of that is the people who vowed never to come back on here but are on this very thread with a new username.
