@Knight the quality of the translation is questioned, I have no opinion on that. The comment is likely not the most kind, but I also do not see it as that problematic in isolation either.
That said, given the timeline I agree that this user better had not commented there.
If they continue to comment insistantly on your posts somewhere bring it to our attention and we'll make it stop.
At the same time I removed the particular comment not to expose that user here.
