Advanced discord starboard bot
https://github.com/CircuitSacul/Starboard
I've been working on this bot for a while. I made this because I can't find very many good starboard bots, and all of the ones that are good aren't open source. I decided to change that.
This bot is made using discord.py-rewrite and aiosqlite. This bot supports multiple servers (another thing a lot of bots were missing), multiple starboards per server, and multiple custom/normal emojis per starboard. I've used it for a while and it is very reliable.
Feel free to clone/fork this bot and self host. I'm not currently hosting, but I plan on changing that.
Please let me know what you think!
