Solved it:
function bpex_hide_profile_menu_tabs() {

if( bp_is_active( ‘xprofile’ ) ) :

if ( !bp_is_my_profile() ) {

bp_core_remove_subnav_item( ‘forums’, ‘favorites’ );
bp_core_remove_subnav_item( ‘forums’, ‘subscriptions’ );

}
endif;
}
add_action( ‘bp_setup_nav’, ‘bpex_hide_profile_menu_tabs’, 15 );

Or better: how can I hide favorite forums and favorite topics for other members, and make it visible only for myself?
