enthrowMaybe I dont know the whole story and I will happily delete this if I don't, but what happens when his mother passes away a third time to explain the lack of progress on a big ambitious project?
That blog post was written by a different person, if you look in the comments you'll see someone mention "artphilia" who responds to the comment. Looking further into it they speak German and wrote a blog post on their personal website https://artphilia.de/das-leben-und-ich/ that mentions the anniversary of their mother passing away in November. On the blog are also more posts about having knee surgery etc.
If you look at the page https://web.archive.org/web/20200512010849/https://efiction.org/2019/02/19/short-news/ it makes no mention of Sidular, who "adopted" the site efiction later on: https://efiction.org/2020/06/07/up-for-adoption/#comment-24310 (even this article now says it was posted by Sidular).
I imagine during the transition smth wasn't adjusted properly so all the efiction articles appear as being posted by Sidular.
