What is this referring to? I tried to find when Jani Patokallio tried to get the people behind archive.today imprisoned, but can't find anything.

Yeah, everyone is freaking out about the (not very efficient as I can see) DDoS attempt, but it was a response to a totally unprovoked attempt to deanon the maintainer which could cost them freedom at least - and us all the only more or less reliable paywall remover.
