I am an administrator on a roleplaying forum and one of the types of roleplay we cater to is smut. As you can expect we run into a lot of trouble with members lying to moderators about their ages in older to avoid punishment and the moderators have to ask an administrator to check the user's age in the edit user page if they have it hidden.
I don't want to take away the member's ability to hide their ages (and there doesn't seem to be a way to at present either) so my suggestion is simple:
In the usergroup permissions either make 'bypass member privacy' fort for profile information too or add in an option to for 'can view hidden ages'.
This would make life a lot easier for me and my stressed out mods.
