Rosie Gray received a "Fail" badge on Jan 04 because their post was full of fail. Like, I mean, the post itself was good. Great even. But the content was, like, kind of "faily." You know? Yeah, I don't really know either.
Rosie Gray received an "LOL" badge on Jan 05 because their post made people laugh. Out loud. Not literally. Why do we say LOL when we don't mean it? That's one for the philosophers, I guess. Anyway, point being, their post was funny. That should have been a way easier point to make than it was.
