link war

The emailing or posting of internet links to others with the purpose of supporting one side of a heated argument.

Joe writes his friend, "At xyz.com/mystudyisbetterthanyours, you can see how my point has been proven and many cases show clear cause and effect."
Mary responds to Joe and begins a link war by writing back, "More thorough research done by abc.net at abc.net/ha_ourstudyhadabiggersamplesize shows that the research in the xyz.link study has been proven to be causally insignificant."
