I followed this link from one of the yukkuri threads in 2chan:
It's a gallery of yukkuris, and the pictures seem to be named in the format [artist]something.
Using this as a reference we can get some names, like:
artist___unknown_14 -> よんばいん (yonbain??)
artist___unknown_20 -> らぶりーペロンペロンあき (lovely-peronperon-aki or lovelyperonperonaki, a tag we already have)
Can someone confirm this?
