I thought the misspelling that contains a racial slur would show up highly, given that it's only one letter off, and the 'a' variant does rank high; but perhaps some subconscious "mental filtering" in the participants avoided that.
(Edit: for an inverse example, consider "dreck": in Yiddish it just means "garbage," but my understanding is that it's significantly more offensive in most Germanic languages.)
It's mostly used for stuff that makes you angry. https://www.dreckstool.de/hitlist is a prime example.
(And you can see the effect of the home office, Microsoft Teams is new there.)
