It doesn't present an obvious notability problem because it's fairly well-sourced, but an argument could be made that his notability is transient, and thus that the article should be deleted under the one-event principle from the biographies of living persons policy.

I won't involve myself directly with the article on principle, since I consider myself biased against Unidan and thus have a minor conflict of interest. I have two reasons for this bias. One is the good reason of opposing celebrity worship, and the other is that when I answered a science question once, he came in later, said some incorrect and irrelevant stuff, and walked out with more karma overall.

(Edit: "thus" → "thus that" to clarify that I'm not advocating the argument but merely presenting it as an example.)
