Two of those posts are merited by
foserfox (the third is not viewable to me). The administration should look into if foserfox is also any of those three people, and ban him if so. I would be surprised if the evidence does not show they are not all the same.
That's why he appeared on the first position there:
He was also auto-banned.
I don't known Russian, but the OP found interesting evidences that plagiariser merited other plagiarisers, and they both got auto-banned.
