Doesn't really make a difference, they do not post there ip addresses publicly so whether ebay/amazon finds this post they wouldn't know what ip addresses they are offering. Plus they seem to be adding new servers every month.
What makes you think they are incapable of purchasing a plan or two themselves just to blacklist the IP ranges? How do you think they blacklisted all the other VPNs?
Looking 4 a vpn, Amazon selling.
