ICANN works closely with various stakeholders, including Internet Service Providers (ISPs) and anti-abuse organizations, to combat spam and abuse. ICANN enforces policies that require domain registrars to maintain accurate WHOIS information, which can be used to track down spammers and hold them accountable. Additionally, ICANN supports the development and implementation of email authentication technologies like SPF, DKIM, and DMARC, which help verify the legitimacy of email senders and reduce spam.
