They also have to write written apologies to their client, and all of the judges who were mentioned in their fake cases, with proof filed in the docket.
And they are the brunt of a very well-publicized lawsuit. The judge is effectively saying that all that publicity is punishment enough; he doesn't need to do anymore. He doesn't need to refer them to the bar for disbarment--the bar already knows about it. (The judge has no power to disbar them himself, he can only refer to the bar for disbarment.)
The biggest surprise is that they didn't get made to pay the defendant's legal fees as well, but that's because defendant didn't ask for any fees.
Oh, and the final punishment... they lost the case--they get no chance to redo their opposition to the motion to dismiss. Arguably, their client can also sue them for malpractice, and their malpractice carrier is likely to prefer to settle that rather than actually fight the case.
