Hello,
I have my own website and have some knowledge on server and the importance of IP address, so i understand completely your requirement.
The using of proxy means that the account creation will be seen as different IP address, and i can do it with some time pause, usually around 5-10 minute with random pause, sometime 5 minute, and in the next account creation the pause is 7 minute, and so on.
I will look forward for any hearings from you.
