Notably, a couple of designs which would fall under that criteria are very important to me and my stories :/ They wouldn't be easily redesigned either, because their appearance or colors are lore-important. So at the moment, tough shit. Hopefully no one makes it a problem. These designs so far include Muskeg, Skink, and Queen Astrapia. The last one I'm the most anxious about, because red/purple/gold is very important to the character, and redesigning her with virtually the same pallet would feel too much like copying.
Ideally I will also be leaving Toyhou.se, as the site is a cesspit (case in point, worrying about "who designed" things I own and/or purchased). I implore users to make sites like this, and want you to know that you can absolutely get bootstrap working with Neocities, if you like some free or P2U TH codes. There's also an Offline OC Wiki project you can check out.
TL;DR people are annoying, I don't trust folk not to be weird, and I don't want the headache.
