Muffy is a Discord bot that temporarily restricts the channels you're allowed to use by deleting your messages as soon as you try to send them.
set your timezone and give a time range (e.g. 9:00am-5:00pm), and Muffy will wait until your local time is within that range, then stop you cold!
add Muffy to your server here, then type @Muffy help
to get started!
