Please ban them, this is absolutely unacceptable. The original author put hard work into his writing, and I still don't see any credit in a majority of their translations. They have published 14 articles in total without any credits going to the original author. It's definitely not the type of news I would expect to be associated with a "hacker". I do not see any links to the original source at http://kukuruku.co/hub/cpp/lock-free-data-structures-introdu...

They are stealing content.

Another user (leephillips) posted the following about their posts: "I went to the site and left a comment complaining about how they stole your article. They deleted the comment, and you still aren't credited. Does HN have a blacklist of sites that steal content or publish only blogspam? I think they should consider it." - https://news.ycombinator.com/item?id=7754641
