Hi, yes there is the filter xmlsf_skip_user
available for this. You can use a code snippets plugin or your theme’s functions.php to add some PHP like this:
function my_skip_authors_sitemap( $skip, $user ) {
$skip_users = array( 12, 15 );
if ( ! is_object( $user ) || ! method_exists( $user->ID ) || in_array( $user->ID, $skip_users ) ) {
$skip = true;
}
return $skip;
}
add_filter( 'xmlsf_skip_user', 'my_skip_authors_sitemap', 10, 2 );
Add as many authors by their ID number (separated by a comma) as you wish to exclude to the $skip_users
array.
