About DroneBL
DroneBL focuses on listing compromised machines, bots, and drones — systems that have been taken over and are being used to send spam or conduct other malicious activities. It is widely used by IRC networks and mail administrators.
Why am I listed?
IPs are listed when detected as running botnet clients, IRC bots, spam zombies, open proxies, or other compromised software. Listings require active compromise detection, not just spam sending.
