Because I just had to give somebody a ban for replacing an entire trope page with a single word, and the only thing I could find on the lists was "putting the entire wiki at risk".
Is such an act really only worth a tempban-on-first-offence, though, or should it be a permaban? It's very annoying to clean up after (even if the cleanup is a simple matter of hitting the "undo" button) and it shows a massive disrespect for other Tropers, but it isn't actually against the law the way the other permaban-on-sight offences are.
