Further reporting of this, especially from Canadian news outlets, go into much further detail regarding this aspect of the court judgement.
The Globe And Mail have a particularly good quote from one of the Facebook reps:
"It's certainly beyond his resources, and we have no illusions about getting all of the money," Mr. Schnitt said.
"We're going to get whatever we can. To the extent that he has resources, we're going to try and seize them."
Mr. Schnitt said he mainly hopes the case will act as a deterrent. "[The ruling] sends a message to spammers and would-be spammers," he said.
"We hope this demonstrates the extent to which we're going to expend resources and pursue people to protect users from spam."
They certainly *will* get this company shut down, and then (assuming they find Mr. Guerbuez, who most news stories claimed was notoriously difficult to find,) they'll go after him.
It may take a while, but they'll do it.
