Back in the day, when we followed the RFCs, we all had Abuse@domain emails that we checked.

Then spammers abused them, and big companies stopped checking them. Now, even I keep my domain registration contact data private because of the hundreds of idiots who apam me about building websites and apps.

I humbly suggest the solution is airstrikes to eliminate spammers, then we can go back to checking our abuse@domain emails.
