Central Michigan University was blacklisted by Comcast when a student’s email account was compromised and used to distribute spam. Attempts via traditional methods to resolve the problem went unanswered. The school finally got Comcast’s attention with a post on the popular social networking site, Twitter.com:

On April 4, a Central Michigan University student’s e-mail account was hacked into and after the spam was sent out, Comcast, a Michigan-based television and Internet provider, blocked all cmich.edu e-mail accounts.

The tweet that solved the problem was sent out by Information Technology Communications Manager Duane Kleinhardt on April 8 at 3:20 p.m. It stated “Cmich.edu e-mail is being blocked by Comcast. Call (989) 774-3662 for more info.”
