In 2 steps:
1. Send all requests through .htaccess to the script router (in PHP) and check the list of banned IPs there before displaying the desired page.
2. When requesting non-existent URLs or with certain words - update the list of IP-bans.
Also, there is a RewriteMap for reading values ​​from a text file for their further use inside .htaccess.
