It actually isn't. I'm not at all sure what I did wrong. At first, I thought it was because of a cross-post with Actifit. But I've just seen another post.

Then I thought that maybe proof life needed to be a selfie, but I've seen plenty of counter examples to that, as well.

Then, since the cross-post I saw in Actifit had the rules image, I thought maybe I was supposed to do that. But again, counter examples prove that incorrect.

Is it just because I missed a tag? And the #alive tag isn’t supposed to be used by itself?
