Other exchanges between the brothers refer to complaints from system administrators from various schools about their spam e-mails and ways of dealing with the complaints. Another talks about how, a spammer who had used a hosting service provided by the brothers had been arrested in a nationwide spam crackdown by federal authorities.

Even after the Shahs learned they were under criminal investigation by federal authorities in 2005, they simply stopped sending spam to students at the University of Missouri but allegedly continued to spam students at other institutions.

The Shah brothers also solicited customers for Ming, who provided hosting and mailing services to other spammers, the indictment alleged.
