Was told about this and checked it out for myself.
Another user sent me a link to a listing. The seller in question only had one animal for sale, but under the “more from” section, there were still animals shown with them attributed to the seller whose listing was being viewed. When clicked, they led to listings from completely different sellers. It seems where it is supposed to be pulling more ads from the same seller, it is instead pulling animals with similar traits from other sellers. This is occurring on both the app and web.
