Why do you only get half a credit per page surfed?

We give half a credit for each page you personally view and the other half to the person who introduced you as a reward for promoting the site. Unlike many TE's we will not jeopardise the delivery rate and credit balances by giving away more than the site can handle. This is why some sites never use up many credits as they have given too many away. We only get one credit in for each page viewed so we can only give two lots of half a credit out.
