Profiles for children under the age of 13 would have been deleted.
New profiles for these children cannot be created until after they turn 13 and even then they will still be UNLISTED and therefore noone can see them.
I personally do not see the point in creating any profiles for anyone currently still living unless they are members of Wikitree.
If you look at my family for example, I have 2 siblings who have both passed, so their profiles can be seen. My remaining sister is a family member so her profile can be seen. My father has also passed so his profile can be seen, as can mine, since I am also a member.
The only family member whose profile is unlisted is my mother and I know she wont become a member, She can barely manage to get around the computer just to use her email and facebook, let alone any genealogical site. But since she is in her 80's, it won't be terribly long before she too passes (less than 20 years most likely) and then I can reactivate her profile as well.
I know the current policies are somewhat draconian, but until we see just how much the EU will police the online privacy issue for anyone who is a potential EU citizen, then we have to play it safe.
