Because it's likely fake. The video shows a brunette in doggie getting fucked. It could be anyone. I've personally tired to buy the video when she's attempted to sell it. Both times, she never sent the video. Both times, I contacted MFC and they refunded me fully.
MFC never refunds more than 1000 tokens, yet twice they refunded me 3000 for Avril's scam. She runs others, such as tips in tPvt or Skypes.
I doubt it's real, and even if it is, I doubt she'll ever actually follow through with sending out the video. I think she stopped "selling" it, because MFC is well aware of her faking this shit and likely stopped the nonsense scam (due to numerous complaints).
