You have to question how to use Bing Rewards to get free gold???
You sign up for the Bing Rewards account, you do X amount of searches daily, you earn credits that can be traded for rewards, rewards that include $3 Live currency codes, 1 month Live codes, or 1 month Live Music codes.
You're allowed up to 5 accounts per IP address, but do NOT make them all at the same time, make them just one at a time, let each one reach Gold status before you make another.
And do NOT redeem rewards on multiple accounts in the same day, they'll ban the accounts for that. .
What's the purpose in owning a Grenade Launcher? The sheer inability to continue life without it ! ! !
