I am curious how you would end up in a situation where you wouldn't be able to open a door due to masses of bodies pressed against your door. Does your home open up directly onto a sidewalk?
Italics is a poor choice for the text, feels like it takes more mental energy to read so it's easier to gloss over.
The color scheme doesn't seem to match the rest of the website, so it's easier to write off as an ad or to just ignore it out of disgust.
The main text on the left, "Homebrew Page", doesn't necessarily register as synonymous with "Unofficial" to me, so even if someone gives it a passing glance they might just assume it's a specific version of D&D and therefore official. I'm not deep in the community though, so most players may already understand what it means.
I found that problem kind of silly. I chose the free will option because it seemed to imply that determinism would just let the people get run over. I don't know if it would have been the same in end, but if the free will option was the only one that saved lives it strikes me as an unfair way to discount determinism as some sort of passive "I'll just let people die" mindset, when arguably the neuron interaction in my brain would make me choose the same result in identical circumstances.
Also voted no, felt like pulling the lever would mean I took part in the inevitable killing, even if the outcome was the same. It would also remove precious time needed for the victims to recount their lives and come to terms with their situation before dying.
Warnings like these can become diluted if the context of these reports are not specific enough. Listing rock climbing free solo deaths on videos of people top rope climbing will get an eye roll from people and make it easier to disregard. It's also not fair to communities that understand the risks of what they are doing to see these reminders of dangers they are already aware of.
