Based on a how-to post by nate_02631, this hack limits the stats that any given blogger can see in the back office on the stats tab. Basically what it does is says "you can't see stats for a blog you can't post into unless you are level 10 in which case you can see everything". That means the default condition of showing stats for blog "none" (which is blog 0 inside the code) will now show an empty page. The list of blogs across the top of the stats page will show blogs the blogger can post into - post with ANY status by the way. It's a neat little hack that exists in 4 parts in 1 file.

Open admin/b2stats.php and look for this bit:

require(dirname(__FILE__) . '/_menutop.php');
?>
<a href="b2stats.php?show=<?php echo $show ?>&amp;blog=0" class="<?php echo ( 0 == $blog ) ? 'CurrentBlog' : 'OtherBlog' ?>"><?php echo T_('None') ?></a>
<?php
for( $curr_blog_ID=blog_list_start('stub');

and change it to this:

require(dirname(__FILE__) . '/_menutop.php');
// HACK ONE
if( $current_User->get('level') == 10 ) { 
	$show_zero_stats = 'show_zeros'; ?>
	<a href="b2stats.php?show=<?php echo $show ?>&amp;blog=0" class="<?php echo ( 0 == $blog ) ? 'CurrentBlog' : 'OtherBlog' ?>"><?php echo T_('None') ?></a>
	<?php
	} else {
	$show_zero_stats = 'dont_show';
	}
// END HACK ONE
for( $curr_blog_ID=blog_list_start('stub');

That stops the "none" option from showing up if you are not level 10 and sets up the ability to display the data later on.

A couple of lines later find this bit:

			 $curr_blog_ID=blog_list_next('stub') )
	{
		?>
		<a href="b2stats.php?show=<?php echo $show blah blah blah

and change it to this:

			 $curr_blog_ID=blog_list_next('stub') )
	{
// HACK TWO
	 	if( ! $current_User->check_perm( 'blog_post_statuses', 'any', false, $curr_blog_ID ) ) continue;
// END HACK TWO
		?>
		<a href="b2stats.php?show=<?php echo $show blah blah blah

What this does is check the blogger's permissions to see if they are allowed to post in the next blog in the bloglist. If they can they get the link - if not then they don't. (I added the blah blah blah because I cut a line in half)

Hack 3 is really neato! Scroll down and find:

	<li><!-- Yes, this empty UL is needed! It's a DOUBLE hack for correct CSS display --></li>
</ul>
<div class="pt">
	<div class="panelblocktabs">

and change it to:

	<li><!-- Yes, this empty UL is needed! It's a DOUBLE hack for correct CSS display --></li>
</ul>
<?php // HACK THREE
if( $blog > 0 ) {
	$show_zero_stats = 'show_zeros';
	}
switch( $show_zero_stats ) {
case 'dont_show':
break;
default;
// END HACK THREE ?>
<div class="pt">
	<div class="panelblocktabs">

This is the part that lets level 10 people see the "none" stats and excludes those who are not level 10 and can't post in any given blog.

Finally, close the new switch near the end of the file by finding:

</div>
<?php
require( dirname(__FILE__).'/_footer.php' );

and changing it to:

</div>
<?php 
// HACK FOUR
} // end of $show_zero_stats switch
// END HACK FOUR
require( dirname(__FILE__).'/_footer.php' );

That's it! I did it on a test installation of v12+p with one dummy user and found it to be functional. I think maybe group permissions might over-ride the hackage but I'm not sure. In other words, putting a blogger in the admin group might let them see stats for "none" but I dunno. Didn't test in that much detail.

Have fun, EdB
