About DF. I can't speak with Alex, because we have some problems before. And I just don't want to speak with him.
They have an IDN section there. It is a subsection of first category. As I know he had some IDNs before, but do not think he like it now, as just many domainers, who didn't make any research id IDNs.
That particular subsection isn't popular. But there can be other situation: people just buying IDNs and trying to not "make attention" to IDNs from other domainers
