I recently stumbled on an artist's page who is using multiple base poses for their YCH auctions. The original pose creator says that they are available to use...but for inspiration or reference. It states in one of their journals that they do not want people using them for commissions. The poses are all obvious as no real change have been made, and they are one of the first pose sets to show up on google. (I lined several of them up and they matched in several places)
Basically, poses are iffy is why I am asking what should be done. Do using other peoples bases warrant an artist beware?
