They want to limit 'fake' accounts as those can take names people want and will use up their available SP for new accounts. I hope they can make it more automated. Just need to find ways that work for everyone. Not all have a Facebook account, but I guess a mobile phone is standard now. I would think they could exploit that other sites have validated people already. Doing it manually will not scale up. We need to reach millions of users to really get noticed and taken seriously.
