Pattern (regex) based mass deletion of discord messages, with UI button!
// enable developer tools (aka chrome inspector) in discord app
// in dev tools get user token from Application > Local Storage (or google how)
// then go to Sources, open Snippets, add and save this code (replacing token with your own)
// use play button in the bottom right to enable, creating a new 'Purge' widget
// discord search in a server/dm (example - from: you, before: jan 2019) and get a postid
// paste in the appropriate input box to delete older/newer messages
const token = "sUp3R-s3kR1t"; //replace with your own
