We've been having a lot of access to "tracker/announce.php" on various subdomains. We used to have some bit torrent abuse, but I've deleted those accounts months ago. Never the less, we are still getting hundreds of requests per second to /announce.php, which is wasting bandwidth. Is there a way to automatically deny any requests to "tracker/announce.php" ?
