Community mod on this instance made a mistake, can't find any form to get it corrected

No info on who, what or why

Modlog finds my account but doesn't link to anything to find out more:

mod Banned @boredtortoise from the community World News@lemmy.ml

reason: Sinophobia

expires: in 5 years

Edit: as the larger issue, when incorrect mod actions happen, shouldn't Lemmy have a system for handling those? Both transparency to the users, and ways to forward the action for an admin to fix
