I suspect they didn't really read my e-mail...

We have a spammer who is spoofing a domain we manage. And they are doing the spoofing through Earthlink. So I send an email to abuse@earthlink.net and instantly get a response:

Hello,

Thank you for submitting a report to the EarthLink Network Abuse 
Department.

We have received a number of reports regarding this issue, and
are already conducting an investigation. Unfortunately, due to 
the high volume of reports that a single incident can generate, 
we are unable to respond personally to all reports.

Sincerely,

EarthLink Network Abuse


So I get an intant automated that shows no one read my letter. So how is it that they know my problem is the same one they have, "received a number of reports regarding this issue, and are already conducting an investigation"?

Or are they so fucked that they have problems with and are investigating every possible problem out there?
