The problem is that with results in the tiles, I can have the race spoiled by simply browsing my subscription or all feeds. I understand why rule 3 exists, because you cannot expect a post blackout simply because someone might have the race result spoiled. That's why the "Race Results" threads are great; the title doesn't give anything away, and the content therein can spoil away.
With results in the title, I have to avoid using Lemmy (as is the case with Reddit) overall. I want to subscribe to and participate in /c/formula1, but with results in the post titles my choice is to unsubscribe and block.
