Comment (by wonderboymusic):

 FYI, here's a good way to debug this in functions.php or whatever:

 {{{
 function a_function( $filter ) { return $filter; }
 class MyClass1 { function filter( $filter ) { return $filter; } }
 class MyClass2 { static function filter( $filter ) { return $filter; } }

 $my_class_1 = new MyClass1;

 add_filter( 'list_terms_exclusions', 'a_function' );
 add_filter( 'list_terms_exclusions', array( $my_class_1, 'filter' ) );
 add_filter( 'list_terms_exclusions', array( 'MyClass2', 'filter' ) );
 add_filter( 'list_terms_exclusions', array( 'MyClass2::filter' ) );
 add_filter( 'list_terms_exclusions', array( 'MyClass2::filter', '' ) );
 add_filter( 'list_terms_exclusions', function ( $filter ) { return
 $filter; } );

 print_r( $GLOBALS['wp_filter']['list_terms_exclusions'] );

 get_terms( 'link_category' );
 exit();
 }}}
