The case defaulted because they were unable to locate and serve the defendants, likely because they are outside the US and not beholden to US copyright law. They didnt show up to defend their case, because why would they? No one expects Annas Archive to comply, because why would they? If you cant even find the server host, let alone manage local law in whatever country that server might be in, then how are you going to enforce any more than a strongly worded letter?

Edit: that being said, my original statement was in jest, a mere fantasy. They didnt have to beg because there was no defendant present. It was likely a very quick case, everyone showed up expect annas archive admins, and a default judgement was made. And then absolutely nothing happened because of it
