General information about Earthlink

Ownership & Contact Info

It is reported that Earthlink has a toll-free number for tracking spam: 888-ELN-SPAM (888-356-7726).

Earthlink is the site that inspired the automated spam reports. During the summer of 1996, the amount of usenet spam from Earthlink became enormous, drowning out many newsgroups. The spam was mostly explicit ads for porn and phone sex, posted indiscriminately to all newsgroups with "sex" in the title, including alt.sexual-abuse.recovery, where it caused no small amount of stress among the participants.

In a sense, Earthlink pioneered the massive flood of spam on the internet. There had been spammers before, but Earthlink was the first major ISP to permit them to continue. There had been rogue sites before, but Earthlink was the first one that couldn't just be disconnected by its upstream site.

Earthlink steadfastly ignored complaints and denied there was a problem. To prove otherwise, I wrote a filter which examined netnews to detect and collate spammed articles. A daily report was generated showing the extent and the nature of the spams.

As a result of the large volume of spam coming from Earthlink, UDP was discussed and eventually implemented. This got Earthlink's attention, and steps were taken (after many promises and delays) to deal with the problem. Spam counts finally declined.

Earthlink admin Harris Schwartz began posting regular reports on actions that Earthlink had taken against spammers. However, the reports did not identify spammers in any meaningful way. It was speculated that the reports were just lists of randomly generated phony account names, used to lull usenet netizens into a false sense of security.

After a few months, Earthlink -- apparently convinced that people had forgotten about them -- stopped blocking outgoing spam, and the problem became worse than ever. In addition, large quantities of email spam were being generated by Earthlink customers. Harris Schwartz stopped issuing reports.

In early 1997, discussion of UDP for Earthlink began again. Partial UDP was implemented. This had the effect of getting Earthlink's attention again. Harris Schwartz and Nick Christenson issued several posts claiming that spam was being dealt with, although it still continued to arrive, apparently undiminished. In July 1997, spam levels finally came down, although as of 1999, Earthlink is still usually in the top 10.

Earthlink has implemented filtering software that works to regulate the volume of outgoing spam. Earthlink can adjust the parameters of the filter to "fine tune" the spam volume. The filters are not used to stop outgoing spam, but simply to reduce it enough to keep Earthlink off of the top of the spam list and presumably safe from another UDP. Earthlink rarely makes the top-5 list anymore, but rarely fails to make the top-10 list.

Dave Hayes has prepared a nice graph of spam over time.

Earthlink, like many major service providers, exerts the absolute minimum effort required to stay off the Realtime Black List and avoid the Usenet Death Penalty. Earthlink allows spam problems to get worse and worse until they are added to the RBL or are threatened with UDP. They then institute whatever measures are required to avoid the RBL or UDP. Sometimes this consists of simply promising to do something about the problem.
