Will it make a difference? Won’t predators just sign up as a 13 year old? I don’t get it. Either get serious about confirming the identities of your users or just let it be. This band aid approach will just make some people complacent.
Approaches like those implemented by Korean mega-service, Cyworld, require identity confirmation. This, combined with MySpace’s new policy, would go a long way in “protecting” children on these sites. Hopefully, Cyworld’s U.S. debut will continue this very effective approach and then MySpace might have to follow suit.
