What a shame. I agree, it's time that some of these sphynx breeders start becoming MUCH more selective about who their kittens go home with, instead of giving them to the first person who waves some $$$ in their face.
The bully breeders I know of (French anyway) would never trade a puppy for anything! They are like battle axes (meant as a compliment). You generally have a better chance slipping past St. Peter than one of these ladies. All this guy/gal is going to get in exchange is another pet from similar sad circumstances. Too bad this case of "what goes around, comes around" makes the animals the victims!
I don't think there's anything wrong with trading a kit for a pup when they are babies, but to do that to an adult who is supposedly a part of your family is not good....but in this poor girl's case, maybe a new home would be a blessing for her.
I check Hoobly often, and have seen that little girl before. Before, they were trying to sell her for $$$ but I guess now they want to trade. I hope she finds a wonderful home soon where someone will really love and spoil her like she deserves.
