A sample of spammers targeting the University of Oregon

This page lists four spammers who repeatedly target the University of Oregon, and who ought to be blocked for those wanting not to receive advertising from organizations which use opt-out mailing lists.

The spammers listed are chosen to be somewhat representative of medium to high volume spammers infesting my email. The links give more detailed information on each one, including links to the spams received (with identifying information removed).

1. MessageReach, sender of 30 spams in less than half a year, spamvertizing eight different organizations. This spammer is the current highest volume spammer of a number of what appear to be spammers for hire.
2. Pushpa Publishing House, sender of 13 spams over the last three years, with increasing frequency. This spammer is chosen to be representative of publishers of fifth rate scientific journals, based in third world countries (in this case, India). There are a number of such spammers, such as Mili Publications, Scientific Advances Publishers, Trade Science Inc., and Science China. Some send significantly more spam than the Pushpa Publishing House.
3. The Principal Investigators Association, sender of about three spams per week during the period November 2009--March 2010. I have email from them (posted at the link) in an implicit but very clear manner admitting to sending unsolicited bulk email. This spammer is my highest volume recent spammer, but there are sure to be others, and it has yet to beat MessageReach's record of 14 spams in one three day period.
4. The Institute for Humane Studies, sender of 37 spams over roughly the last two years. This spammer is a high volume representative of the "miscellaneous" category. MessageReach and the Pushpa Publishing House are probably spamming most of my department (and targeting other departments on campus with different spams), and the Principal Investigators Association is probably spamming addresses it harvested off the NSF, NIH, and similar websites (they publish email addresses of grant recipients), while it is far from clear how the Institute for Humane Studies decided to add me to their spam list. There are other spammers like them.
