What it detects
IP addresses that have been the source of spam reported through SpamCop's reporting interface. Listings happen quickly when a sufficient volume of complaints arrives in a short window.
Listing categories
Single-purpose list — listed IPs return a 127.0.0.x response. SCBL doesn't categorize by spam type; the only signal is presence vs absence.
How to check a listing yourself
Query the reverse-octet form of the IP at `bl.spamcop.net`. SpamCop also publishes a free per-IP lookup at https://www.spamcop.net/bl.shtml.
How to get delisted
Listings expire automatically 24 hours after the last spam report. There is no manual delist request — fix the underlying spam, then wait for the auto-expiry. If complaints continue, the cycle repeats. Persistent listing means the source hasn't been remediated.
