He replied to you in that thread, and though I haven't looked any deeper than the links you posted, I have a feeling what you reported was not in fact plagiarism.  I could be wrong--but the mods haven't acted on it, and they're the ones who will decide if you were right or wrong.

I'd also add that not all of Ratimov's posts are like the ones you linked to in the OP.  I checked his merit history because I knew I'd given him a few merits here and there, and he can and does write original content that isn't just a huge article with a citation at the end.  The last merits I gave him were for a thread he started, calling out a scam, and it looks like he put a lot of work into the OP of that thread--and I'm not the only member who merited him there, by the way.

Ratimov isn't a shitposter, and I'm not convinced he's a plagiarist.  Not sure why you've built up such a grudge against the guy.
