This probably wouldn't work as most sites allow the IP to vote once each day.

 

This would fall under multi-accounting for economical gain. Therefore it is illegal.

After talking to other staff members we have found that as long as this is all done on two separate IP addresses and both accounts are owned by different people this is fine, although we are able to look into all of this so make sure you have checked out all of the rules around multi accounts and things of that nature, just so you know that you aren't breaking any rules, but with the circumstances I have stated above this is fine, but be careful with things like this as it can be seen as multi accounting.
