The first step is obvious: go to Reddit and make sure that you’re logged into the account you want to be deleted. Once you’re logged in, click on your account name on the top left. This will open a drop-down menu, and the next thing you should click on is user settings. This will take you to a page with multiple tabs. Make sure you’re in the Account settings tab and go all the way to the bottom. You will see a red button that says, “DELETE ACCOUNT”.
