Overview
SEM Black was the general-purpose spam source blacklist operated by Spam Eating Monkey, tracking IPs with confirmed spam sending histories. Unlike SEM Backscatter (which focused on NDR abuse), SEM Black covered direct spam senders across a variety of categories.
Spam Eating Monkey operated several complementary lists, and SEM Black served as its primary IP reputation list for general spam. All Spam Eating Monkey DNSBL services have been discontinued.
How It Works
Spam Eating Monkey populated SEM Black through its spam trap network and data sharing arrangements with other anti-spam operators. IPs required multiple confirmed spam incidents before being added, providing a degree of protection against false positives. The list covered a broad range of spam types from bulk commercial email to phishing and malware distribution.
How to Get Delisted
SEM Black is no longer maintained. No removal action is possible or necessary. Spam Eating Monkey's full suite of DNSBL services has been discontinued. For current spam reputation issues, consult actively maintained blacklists such as Spamhaus ZEN or Barracuda.
