I don't know the exact situation obviously, but isn't it possible that the poster simply wasn't able (or didn't know how) to add the strikethrough, but had the expectation that anyone who knows about this form knows, and the replying commenters were indeed people who did instantly recognize that jumble of characters, and acknowledged it?

Like, I didn't know about that form of the loss meme, but now that I know it's loss if you add strikethrough, I'm pretty sure I'd recognize it even without the strikethrough.

Yea, I was able to tell what it was without the strike-through. It's not necessary. In fact, it's one of those memes where the meme itself is about recognizing it in super obscure formats so that's where my mind and most peoples' minds who are familiar with it would go to. I HIGHLY doubt it's a bot thing.
