I've also noticed over the years that many of the models used, their creators request that they be mentioned in the least and are not. It's one of the reasons I don't create and offer here anymore. It's in full bloom where many...and often well known artists, use other artist's models and do not even mention them as their source model. Personally I think it's disgraceful and should not be allowed. But it's been going on so long that I think no one cares anymore...so much for copyright integraty.
