How do ISPs participate in anti-abuse groups?

ISPs participate through M3AAWG membership, abuse desk operations, and direct relationships with blocklist operators. Large ISPs employ dedicated abuse teams managing complaints, investigating compromised accounts, and coordinating with external organizations.

Participation includes: contributing detection data to shared pools, implementing recommended practices, responding to abuse reports from external sources, and participating in industry working groups developing standards.

ISPs hosting email services have dual roles: protecting their customers from receiving abuse and preventing their infrastructure from sending abuse. This dual responsibility motivates active anti-abuse participation. ISP engagement strengthens ecosystem-wide defenses.
