In a blog post today, AOL announced they are changing the from address on their FBL emails from scomp@aol.net to fbl-no-reply at postmaster.aol.com. This change will take place on January 16th, 2017.

Abuse, triage and data sharing
The recent subscription bombs have started me thinking about how online organizations handle abuse, or don’t as the case may be. Deciding what to address is all about severity.
