No, this particular case has not been reported. But I had a similar case earlier from the Pakistan section. Also plagiarized. I reported it in the moderators section, but there was no response to my request, even though I gave the example of two cases of plagiarism. So I saw no point in filing an application against this user, as it would likely be ignored as well.
Could it be that moderators are becoming more lenient in decision making these days. Maybe theymos had issued an information/advice on this after it was discovered that he invalidated reports that are 6 months old.
I can't tell you anything about that. Only the global moderators themselves can comment on this. As for any instructions from theymos also can not say anything. I have not heard about it.
