have you tried image searching for her on google?
a few days ago i learned that my OC Shey was stolen around january. The image that was used to sell her as an adoptable was a commission artpiece by a dear friend of mine.
It looks like this: 
if you see this character anywhere please DO NOT buy/use her. She is a very dear OC and I made her on new years eve. I can prove my ownership of her as I did create her and she is on my TH character list.
We don't know much information other than that she was sold in January on FA. I only managed to get in touch with one(?) buyer, who claimed they didn't know anything and they didn't give me any information on the seller either.
the only information I recieved was that their username had something with "cupcake" in it, but that could literally be anyone;; ._.;;
so yeah if you see this OC and it's not under my name it is very much stolen;; i am trying to track the seller even though we have no clues to them other than this;;
would love to know if anyone has seen it or can potentially report the theft;; as i dont know what else i can do on my own.
