The first step is to new email addresses. Use burner phones to verify your burner accounts. You want as many layers of subterfuge between you and the account as possible. Plausible deniability is the name of the game.
Selecting the right username for your burner account is critical to its success and your anonymity. Too many people provide clues that the media can use to track them down. You most likely don’t want that.
You have your account set up to a fake email with a basic-ass password. Now it’s time to put it to use.
First, you must establish your voice. You may choose a voice that is slightly accusatory that will bring enough attention to provoke response, but not enough so that it will be remembered the next day. You want to run perfectly in the middle of everything without tipping people off. The aim is to have fun, but not too much fun to get carried away.
