If an unnerving sight sits around for long enough, there's a very good chance that someone will take a picture of it and post it on the internet. Maybe they think if they had to see something messed up, then the rest of us do as well. Or maybe they just want confirmation that they're not alone in their discomfort.
In any case, there's something about their discovery that made it impossible for them to look away and pretend it didn't happen, and that feeling is obviously infectious because it's what keeps us coming back to stuff that we'd never want to meet in the wild.
Fortunately, some folks made that sacrifice for us.
