CleanLeave

CleanLeave helps keep your server clean by automatically removing the join messages of members who leave the server. It allows for you to have join messages in your chat channels without the risk of members who have left cluttering chat with unneeded join messages. CleanLeave will also delete join messages of members who are in Discord's native timeout as a measure against spam.

CleanLeave does not have any commands, it is just plug and play!
