Semi active doesn't change the price at all, it's still a dangerous pet and would probably have to be traded away. A VWN will not effect the price if it's semi active.
Most likely it'll get reversed. "Not well-known" doesn't mean anything,still they can file a ticket and create boards about it.
If your lucky enough to get off with it try trading for a UC Plushie.
I had a 4L high-end Darigan that I was legitly trading, I wasn't able to get anything close to UC Plushie offers though. I got a very high end faerie offer but that was about it. You might be able to depending on how nice the name is though I guess? Not knowing the species I couldn't really say.
