I'm looking for research for the experimental study and this is a weird study I saw:

Grov, Christian. "Make me your death slave": Men who have sex with men and use the internet to intentionally spread HIV. [References]. [Journal; Peer Reviewed Journal] Deviant Behavior. Vol 25(4) Jul-Aug 2004, 329-349.
WTF?

Here's another odd one on the same topic:

Gauthier, DeAnn K; Forsyth, Craig J. Bareback sex, bug chasers, and the gift of death. [Journal; Peer Reviewed Journal] Deviant Behavior. Vol 20(1) Jan-Mar 1999, 85-100.

Hey, this is fun- an article on ebay:

Dunn, Sharon Ann. Do losers matter? an experimental look at the impact of control and scarcity on satisfaction with an online buying experience. [Dissertation Abstract] Dissertation Abstracts International Section A: Humanities and Social Sciences. Vol 64(1-A), 2003, pp. 208
