AutoPublisher

A bot that will automatically publish every new message in your announcement/news channels to other servers who follow it. An excellent solution for servers who rely on bots (such as RSS feeds) or webhooks to publish their news, allowing your moderators to get some rest from manual publishing.

To get started, simply invite the bot to your server and run the /permissions command. This will show you all of the permissions, the bot needs to function (View Channel, Send Messages, Manage Messages and Read Message History).
These permissions don't need to be set globally. You can set them in each channel you need the bot in. That's the reason, why I don't ask for these on invite.
If you set the permissions globally, then the bot will publish messages from all of your announcement-channels.

Keep in mind...

The bot can only publish 10 messages per hour per channel (just as users), this is rate limited by Discord!

If you want to temporarily stop the bot from publishing messages in any of your announcement channels, just disable its' View Channel permission in a desired channel and enable it back when you're ready.
