That was his handle: wasfree.
Yeah, I think the screen name was "wasfree." And he started a file under "magnum opus dejure" to post this. I happen to know that when a member starts posting flame, a moderator looks at the "member since" date. Long-time members are given a bit more leeway than newbies, who (it is safely assumed) have just arrived from DU or SC to stir up trouble.
If he's been a member since 1998, a lifetime ban would certainly have to be well-earned.
