About uploading songs to Nico Nico Douga

I don't mind if you use my UTAUloids sing, it makes me very happy, also I don't mind if you want to upload the songs to either Youtube or Nico, but PLEASE! I beg you! Don't upload songs if you have used Spark! I don't mind if you upload songs if you have used Stella, but not Spark. The reason? because when I debuted Spark on Nico he didn't got a warm welcome. I got comments saying that he has a disgusting voice and I took the decision to keep him off Nico. So please please please DON'T upload Spark's songs to Nico, it makes me sad reading that kind of comments since I put a lot of effort recording his voicebank. As I said I don't mind if you upload Stella's songs because nico users kinda tolerate her voice (I think they got used to her) but is not the case with Spark, I just want to keep him Youtube exclusive, out of Nico because it's hurtful reading comments like that, I had to remove his debut song because of that.
Thank you.
