User blog:Melonramune/Posting Youtube Utaite?

Just making sure, can we post pages of Youtube Utaite? Like some Youtube Utaite like Mikutan or Ashe have NND accounts and actively post on them, but they originated from Youtube. From pages like this, it seems to me like we can post pages on Youtube Utaite...? [I'm not so sure though sorry ><;]

And also, is it okay to post pagers of VOCALOID utaite such as Rockleetist, who only have Youtube accounts but are renown on NND?
