The Clapper app is known for being somewhat a freedom of speech app, but your freedom to delete is non existent. The app does not have a section within your account settings to delete. To do it, you must email them. When you do, as I found out, they will email you back wanting to know why. No matter what you tell them; they do not delete your account and just give you the run around.
This has happened with many users that have grown tired of the glitchy program. No matter how many times you hit "not interested" it will keep showing you the same stuff. The app has a tendency to Freeze up while checking notifications, or going over to a persons page to block them because you do not wish to see their content.
