I can understand your reasoning, but you need to remember that the key to bone marrow donation is getting as many people as possible on the register. That means making it easy to sign up. The simpler the process, the better. Making a web form complicated, demanding, or asking for too much information is a mistake people make right across the internet all the time, and it's shown to cost them customers. I've definitely seen articles about how slightly tweaking the wording of forms increases sign ups by some percent. Why would giving bone marrow be any different? Criticism of the bone-marrow donor sign up process should be welcomed. The user stated that they did eventually get through the process, so your criticism of them is unfounded. Would the world really be better if people didn't criticise processes because they were somehow linked to charitable good? It's not petty and disgusting to criticise a flawed process, whatever it's for. If this was someone's startup and it had that kind of convoluted signup process, would anyone complain about criticism? No. Surely a process that could result in saved lives is more important to get right than someone's start up.
