# Detox
Toxicity and profanity filter for Discord. This bot makes use of the [Perspective API](https://www.perspectiveapi.com/).
Add exemptions to specific roles and channels and customise percentages per server to log, warn or delete messages.
Detox also supports a blacklist system implemented with Regular Expressions.

This bot was made in a rush and should be considered unstable for production use. As the days go past I will attempt to improve it.

# Invite Link
If you'd like to use the bot how it is, without customising it feel free to [click here to invite it to your server](https://discordapp.com/oauth2/authorize?client_id=693392652456034384&scope=bot&permissions=388096).

It requires several permissions, the biggest being managing messages. You are free to remove any that you think are too dangerous. 
Note that the bot will not be able to function entirely if you do remove them.

# Installation
- Install mongodb server community edition
- Clone repo
- Copy `example.env` to `.env` and supply a Perspective API key, along with Discord Bot Token
- Install node modules - `npm install`
- Run typescript compiler - `tsc`
- Start with node - `node ./dist/index.js`

# Usage
When the bot joins a server you'll need to set the log channel before anything can happen.
All commands are case insensitive. Arguments to them are not.

All commands excluding !SetToxChannel and !RemoveTox **must** be executed from the log channel.


# Blacklist System
Detox also features a blacklist system that uses regular expressions with the global and case-insensitive flags enabled. 
First the blacklist is checked then profanity is checked. 

If a regular expression has a match on the message then the message is deleted and no warning or log is sent to the tox channel or user. 

The profanity filter is not run against the message if a match from the blacklist checker is found.

It is important to note that exempt channels and exempt roles are still considered by the blacklist checker so if someone has a role that is exempt they are also exempt from triggering the blacklist checker.

Blacklist channels are the list of channels that are monitored for blacklisted messages. By default a channel does not get checked against the blacklist.
