We all know those people who join and do song requests that are meant to troll the streamer or the people watching (Racial slurs, peaking music ECT).
I recommend making a public black-list people can opt-in to use that will download a black-list file from the webserver that will be updated by mods? Users? Up to the guys at deep bot.
This way everyone can pitch in to black-list troll songs and improve the security of the song request system for everyone.
