I found this warning clear enough.

I think it's a good thing to include these images, we've become too used to content moderation that we're desensitized to a lot of the atrocities that are still happening daily around the world.

The images are worse than that. A picture taken at a distance of someone being shot in the head is easier to see or scroll by than a closeup of a head blown in half.

The phrase sometimes gets a bit overused. I wasn't fully prepared for some images either.

Distressing can be pretty subjective, and I was definitely not expecting to be THAT distressed. Figured other people might also be caught off guard.

I see where you’re coming from, but perhaps something like “close-ups of mutilated bodies after execution by large-calibre weapons to the head” would give more of an indication. I didn’t expect the gore, just a wide shot of someone with a gun to their head, a bit like the famous one of the add-hoc execution in the street in Vietnam by Eddie Adams.
