They might, they might not. But the key thing is "anything that can be claimed without evidence, can be dismissed without evidence". Jpg posting is a plague that shares too many symptoms with AI-posing, so barring proof it isn't AI, it can be dismissed as AI.

Maybe it's real. Maybe it's even real AND actually portraying the event claimed. Maybe it's even real AND actually portraying the event claimed AND from a viewpoint that isn't biased in any direction.

But we'll never know, because they're a filthy jpg poster.
