This bot was written with pycord. To install it run python3 -m pip install py-cord. Setup the bot by filling in the missing info with python3 ./setup.py and providing the needed values. To run the bot, python3 ./bot.py. I realize security could be improved with environment variables but this wasn't meant to be hardened as that's not really needed.
This bot was written to keep track of how many times people are quoted in a specific channel. In order for quotes to register they must contain mentions for every person being quoted. Multiple people per message are allowed and will not cause an error, but a limitation in either Discord's API or pycord prevents multiple mentions of the same user (see #1).
I may fix the hardcoded Channel ID at some point (see #4), but until I do, the Channel ID will be set by setup.py, or can be set to a List of IDs without too much difficulty.
NOTE: By default the bot runs silently. This means quotes will only be acknowledged by the reaction, and a message won't be sent back for invalid quotes. If your users are new to this bot, consider uncommenting the revelant lines under the on_message() function for a while.
Also note that this code is in no way optimized. I'm sorry.
