Many of his new posts are in the Russian language therefore non-Russian speakers will not be able to use as a comparator his previous posts to new posts.

Has anyone sent a message informing him of this thread or asking him to defend himself? That would be a good starting point, if he declines or whatnot, then we go from there. I'm sure he will decline to comment, but someone should at least inform him so he is aware.
He's fully aware. There is a good chance that the alleged new owner isn't quite as proficient in English, and posting via Google Translate / ChatGPT is cumbersome.
