/*
/   Welp, Discord used Yukiko-dev-team as an exemple for their new ToS enforcement. because they are releasing a new feature with YouTube.
/ 	So I guess I have time again?
/ 	funyn they wont reply to the ticket they TOLD me to make.
/ 	so this might be last update of this bot and then I leave Discord to use LINE, messenger, or something else.
/   Here is the link to my LINE account :) https://line.me/ti/p/FOBYHR9htn
