Replies to users with "False!" when you mention the bot... That's it.
This is pretty much a carbon copy of the Truer bot I made previously.
Start by cloning the bot and going into the falser-bot directory.
git clone https://github.com/Senither/Falser-bot.git
Next, install the dependencies using Yarn or NPM.
yarn
And now run the bot with your Discord token following the file name.
node bot.mjs <your discord token goes here>
And that's it.
For another dumb bot, check out Smiler, the bot that replies with a smiley face to everything, or Truer which just replies True to everything.
Falser bot is open-sourced software licensed uder the WTFPL license, just do what the fuck you want to.
