Posts in inaccessible forums

Hi !

This is my first report in this section so I hope it will be helpful.

Example description:
Lets say we have one or more forums (sections) that are available just for a special member groups. They are not visible for other users or guests.
Lets say User1 is a member of the special group and he has an access to this hidden sections. He wrote 2 posts only in this special forum.
Now, I'm a guest and I would like to see User1's profile. In the 'User activity' field I can see 'Posts: 2'. So I click on 'Show all posts'. Then I get the following message: 'There are no posts by this user in this forum.'
Of course I shouldn't be able to see his posts as I am not a member of this special group. But... it is not true that 'There are no posts by this user in this forum.' There are posts written by this user, just in a special section that I am not allowed to read. So in my opinion there should be a message saying: 'Some posts written by this user are located in forums that you have no access to.'
