Hmmm. It bothers me that a site like that exists. I'm a huge supporter of vaccines and would be vaccinated against everything if I could, but I doubt that posting the names and stories that way is doing anything to encourage a change in people's behaviour. Rather, it more likely only hurts the deceased family members who are mourning a loss. That loss is real, irrespective of whether or not the person who died was an antivaxxer. Not trying to be a wet blanket, but I think sites like that primarily stir the pot and don't address the main issue of educating people about the scientific basis for being vaccinated.
