I'm a member of the alumni group for my HS on FB. This is an official group from the school.Recently, they sent a note about updating their records with new addresses, etc. Morons are posting their addresses (and that of friends, relatives) ON THE PAGE'S WALL. As in, anyone who is a member of the group (and maybe others, depending on the group settings?) can see the addresses.I posted a note recommending a PM to the admins instead. WTF.
