something like this may work – just enter in the user_id of the admin account and the activity items are removed from the activity array.

function my_denied_admin_activity( $a, $activities ) {



//if admin we want to know

if ( is_site_admin() )

return $activities;



foreach ( $activities->activities as $key => $activity ) {

if ( $activity->user_id == 1  ) {



unset( $activities->activities[$key] );



$activities->activity_count = $activities->activity_count-1;

$activities->total_activity_count = $activities->total_activity_count-1;

$activities->pag_num = $activities->pag_num -1;



}

}



/* Renumber the array keys to account for missing items */

$activities_new = array_values( $activities->activities );

$activities->activities = $activities_new;



return $activities;

}

add_action( 'bp_has_activities', 'my_denied_admin_activity', 10, 2 );
