I can't tell for sure if it's plagiarism or not, but
this post looks "from another world":
a lot of specific terms (I think) and quite different from this user's other posts.
However, I couldn't find a match in my web search, but maybe you guys are more skilled in this.
This is a call for doing a check, not a proper report. If it's not OK that I've posted this here, I don't mind if my post gets deleted.
