That's why most banks will require a personal guarantee from the owners of a small corp/LLC.

No, the "merits" had already been decided--due to Spamhaus' default (for whatever reason, they didn't properly argue to the court that they weren't subject to its jurisdiction), e360 had already "won" on the merits. The only question remaining was how much harm they had suffered from Spamhaus' actions--and since they didn't produce any appropriate evidence on that subject, they were awarded $3.

Spamhaus almost certainly would have won on the merits, if they had competently argued them. Alternatively, they probably would have gotten the case dismissed for lack of personal jurisdiction, if they had competently argued that. As it was, they didn't competently argue anything until it was too late to avoid judgment against them.
