I don't think that Kagi role could be deciding what it's official, and what it's not; we've had some other discussions about similar issues, and I'd prefer Kagi to simply do a really hard work: offer me a list of results strongly related to my search, listed by priority or by others criteria (I'm not joking, this is a really hard work I think).
So, for me no special mark attached to results, for whatever reason.
(aside, my personal feeling is also that I wouldn't be comfortable using a search engine that cares particularly about piracy, that I don't approve at all...but it's only my point of view)
