IP Address Filtering - Problem Continues

Ave, Unfortunately my problem persists. The reason my script was recording "NULL" as IP address was because I was using $REMOTE_ADDR. When I started using the correct syntax, i.e., $SERVER['REMOTE_ADDR'], it actually did start recording the IP Address of the spammer. The problem is, the spammer is using multiple IP Address. His IP Address changes every 6 - 8 entries. I have so far recorded 5 different IP Addresses of the spammer. Although I can create a Database and keep adding his IP Address to the database, and run a check from the Guestbook script to scan against Blocked Addresses, It¹s not the most efficient method in the world. What other logic can I apply to automatically block the spammer? Or at least have a more efficient method of blocking the Spammer and his IP¹s? Thanks. On 3/30/06 8:41 AM, "Rahul S.
