I suggest there be a "rubric" for mute times because it seems as if staff just mute people for as long or short as they like right now. For example:
Spam 1st offense -> 5 minute mute
Spam 2nd offense -> 15 minute mute
Spam 3rd offense -> 30 minute mute
Language 1st offense -> 10 minute mute
Language 2nd offense -> 30 minute mute
Language 3rd offense -> 1 hour mute
