Mark long comment URLs as spam
If a comment author URL is longer than 50 letters WordPress automatically marks it as spam with this short function.
/** * Snippet Name: Mark long comment URLs as spam * Snippet URL: https://wpcustoms.net/snippets/mark-long-comment-urls-spam/ */ function wpc_url_spamcheck( $approved , $commentdata ) { return ( strlen( $commentdata['comment_author_url'] ) > 50 ) ? 'spam' : $approved; } add_filter( 'pre_comment_approved', 'wpc_url_spamcheck', 99, 2 );
