Public VPN are not cutting it these days for those account creations. Proxies and anonymous IP are also getting banned left and right. We are setting up an operation to setup VPN servers with static residential IPs. Each IP we offer will not be shared with anyone else and we can help you setup your virtual machine to only connect to that residential IP so your real IP won't leak to cause account linkage (Facebook, Google...).
The it does take time and effort to get this operation going and the question is, how much would you be willing pay for this service?
If they really work well and are exclusive, charge enough to make it work with less customers so they stay powerful.
$40 - $50 a month range?
