Are clicks from outside Twitter valid?
CPC ads are for posting to Twitter and a publisher cannot copy and paste the ad to any place outside Twitter.
However, if you have your Twitter tweets integrated with your Facebook, MySpace or other social networks, FriendFeed or your own blogs, and your tweets are automatically fed and displayed there, clicks on ads from these sites may be acceptable, if they are valid clicks by real users and there is no suspicious click patterns or excessive number of clicks.
