I thought it was too, but the permissions set in Classifieds are set to allow seeing it, but not interacting, at least for some usergroups. It was 4am when I looked, though, and the nature of the way the permissions system works means that it can be set as visible in one place, but denied somewhere else and inheritance rules mean the latter denial overrides the permission. It's quite tricky to get your head around, and for each of several usergroups. When I get a sec, I'll have a closer look when it isn't 4am.
