How to Delete ALL Your Reddit Comments!

To unsend a message, hold down on it while tapping and holding, then choose “Remove.” You have the choice of “Remove for Everyone” to retract the message, or “Remove for you” to remove it from your inbox.
Click the username link in the upper right corner of your screen, then select the comments option. This will take you to a list of all of your remarks. Click erase at the bottom of the comment you wish to delete.
You can now access your comments by going to https://www.reddit.com/user/me/comments/. Under your Karma, you’ll see a new ‘Delete all my comments’ button. To begin the deletion procedure, click on it. Nuke Reddit History will turn each of your comments into a jumbled mess of random characters before removing them one by one.
You can remove your own or someone else’s comments simply by selecting the three dots to the right of your comment and then Delete from the pull-down menu. When you delete a comment or post, you’ll be prompted to confirm your decision by clicking Yes on a confirmation message that asks if you’re sure you want to delete it.
To permanently delete Messenger messages, go to your settings and select “Delete Account.” The “Unsend” option will remove your message from both ends. In other words, unsending a message on Messenger will result in the permanent deletion of your message on your end and the receiver’s side. There is no alternative way to do it.
