Web application - automation limitations

Hi

Let's say I have a web application that does creation of millions of email accounts at for example Gmail. This web application is hosted at my hosting account at for example Hostgator. What can I do to prevent my Hostgator account from being flagged and my hosting IP to be banned?

Buy server proxies through a provider in the BST section (GenerationX and Packetflip I can personally vouch for), then add a bit into your code to make it rotate through them at a reasonable clip every X number of account creations.

There's a set limit I think to how many you can make per day before they give you any shit, I don't recall exactly how many but you can probably figure it out through looking around and tinkering.

a few ideas here to make this happen
1) get hosting through a bulletproof hosting.
2) build proxy rotation into your script itself. its not hard libcurl has proxy built in
3) stay under the radar. only make so many at a clip. then time out. this can be done best via cron job and or random timing.
