It appears Aircheck and Jammer1954 have been given up:
Times-Picayune gives judge data on two online commenters ~ Gordon Russell
Gordon writes a pretty good story recapping the order and then some. But it was the bottom of the story that I thought was most interesting and true based on my experience here at Slabbed:
While the email addresses that “aircheck” and “jammer1954” gave nola.com might provide clear evidence of who they are, they might also prove useless. Reade said free services such as Guerrilla Mail provide disposable temporary email addresses for people who don’t want to give up their real email addresses to avoid receiving spam.
But he said such “anonymizing” measures are usually taken only by tech junkies and paranoid people.
“Most people are really lazy and just do this kind of crap from work,” Reade said.
