An amateur implementation of Randal Munroe's r9k system for discord, inspired by Signal and written entirely in rust.
When considering the content of the message, the bot will filter out any character aside from A-z (Case insensitive) 0-9 and trim anything enclosed by <> angle brackets.
In the raw message content sent to a discord bot, all channel/user mentions and emojis get enclosed by angle brackets.
Practically, this means that the bot ignores all punctuation, whitespace, mentions, and emojis, which means messages like Yeah! Sure thing! @User and yeah sure thing. 😀 are both recorded as yeahsurething.
Attachments are currently not considered by the bot when gauging originality. For now, one will have to include a message with any images sent.
After a user sends a violating message, the user's streak will be incremented by 1 and will subsequently get muted for 2^(2 * streak - 1) seconds.
This mute's the user for 2 seconds and quadruples the duration for every subsequent violation.
The user's streak will decay by 1 every 6 hours until it is back to 0.
(For those who are not knowers)
The 9084 bot compares the messages you send in specific channels against a database of every other message that it has logged. If the bot decides that a message you've sent is similar enough to a message that anyone else has sent prior (meaning the message is "unoriginal"), it delete the message and will mute you for increasingly long durations. See this article for the philosophy behind this system.
