The post text is supposed to be right underneath the "This is an automated archive [...]" and the following few links. Dunno if that depends on the subreddit. Or if most posts just don't contain text as they're a bare link or image...?! But I see content attached to several posts mirrored by the Lemmit Bot.

I think there's just a lot of posts with the entire text in the title and it's just an image or link. I just scrolled through 25 of them and the original doesn't have any text either. And then there's some with text and the text gets copied. (Example: https://lemmit.online/post/8076620 )
