How exactly does your inability not to swear in every single message you send prove that bot's word filtering should be removed? It won't delete messages containing "shit" by the way, banned word list mainly contains racial/homophobic slurs + some words like "fuck".
Toribash is a verified discord channel which implies certain message quality standards. There's no filtering in #off-topic, so if you're that bad at keeping your messages civilized you can still chat there with no problem. Keep in mind that staff members will still likely delete your messages if you start using obscene language too much / in order to harass other users.
