They haven't even named a defendant except for some random archivist [0] they have no evidence against. I get suing John Doe for discovery and injunction purposes but how can they even be awarded damages - no show or not - without identifying the defendant.
You forgot to add a link about the accused archivist, here's an article[0] about her denial of any connection to the group. (One of their arguments is that she has a github account named "anarchivist", which is a pretty sick name)
This is also why having a default judgement delivered against you for failing to show up generally isn't great.
