I can't count the number of times I clicked on a dead comment's user profile only to see a shocking number of dead comments, sometimes going back months (years, even?). Out of some morbid curiosity, I suppose, I'd just keep clicking on 'more' and regularly the number of comments would be in the hundreds. One the one hand, this approach seems very effective, but I can't help but feel pity for this person and even some sense of cruelty if I were to implement such a feature myself (although I probably would). Of course, I'm also the person in real life who will eventually 'engage' with that "one person" in a group who everyone has been tuning out for a while. I don't get the impression doing so matters to said person, because clearly they're oblivious, but at least it makes me feel better or less guilty.
