I doubt anyone will. the former translator got married and moved to another country according to rumors Many are against someone stealing his work
The rule though is that you don't take someones work within 3 months of the last update right? It's been close to half a year, and the page administrator where the novel has been updated so far is unable to contact him, so by your difinition it would for that reason remain eternally un-translated.

While I don't really remember the story, I do remember I really enjoyed binge reading what was translated before the translator got married and stuff.
