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."

Link War 

On internet discussion and debate forums, a form of argumentum ad lapidem or argument of the stone used in response to another poster to dismiss that posters argument without review or consideration. Generally, this is done in response to posts that contain links to material that supplement, explain, and support the points of the poster providing the links. The responding poster has no valid argument for the material linked and dismisses it without review of the merits of the material.

His argument was shredded and all he could do was post Link War.
Into the Night could not respond intelligently to the post so he dismissed it all by declaring it was a Link War.
