I cannot make any post/comment containing the string [slash]etc[slash]passwd on lemmy.world

When I try to submit a post or comment containing the string [slash]etc[slash] passwd, the submit button goes into a loading state and spins indefinitely. The request is blocked by Cloudflare with status code 403. I can’t even search for the forbidden string. You have to check dev tools to find out what went wrong, this error...
