Is there a protocol for getting pixiv artists identified? I read it on the forums, but the couple times I used it it didn't seem to work out overly well. So any suggestions?

You can either use his username (えすうりゃ -> esuurya) or the account name (rush8934).

If someone finds out what his real name is they can easily edit all the tagged images.

Oh yeah and here's a kana/kanji-> romaji converter thing:
