Some merchants never updated their categories after the Marketplace change. As for Frazella's presence in the Millenium Girls category.. well, that's because Vicki's textures work on the Mill girls, and I have used Frazella on the Mill girls on several occasions. Check my gallery. ;) Same for Stone Maidens. I used the stone textures on the Mill kids, so while the textures shouldn't be purchased SPECIFICALLY for the purpose of the Mill kids, I don't see why saying that the textures will work on the Mill kids is a problem. However, I don't put my products in, say, the MIchael category. I consider category spamming to be abuse, but I honestly don't think anyone does it on purpose. I think a lot of miscategorized products are simply old ones that were never updated.. Edo, VV, etc, are all older works.
