asp.net mvc - Facebook FBML <fb:name> tag not working for some users -

-

i have weird behavior when using facebook <fb:name> tag in application.

for example have list of users rendered on web page , using <fb:name> fbml tag generate link user profile. example generated link for:

<fb:name uid="627670450" useyou="false"></fb:name> be: http://www.facebook.com/profile.php?id=627670450 , facebook display:

"this content unavailable"

and know user exists because can verify it: http://graph.facebook.com/627670450

for other fbuser id's generated links works fine example:

http://www.facebook.com/profile.php?id=100000032667354 displays user profile page no problems.

any ideas why users facebook wouldn't display profile page? on front end i'm generating around 100 users , it's doing half of them. should add profile <fb:profile-pic> tag works fine every user can see users profile images.

the reason can think of privacy settings user use block profile displayed i'm not sure if case.

any suggestions appreciated.
