...ok so don't actually count the credit until some real uploading has been 
done.
If you want to be really paranoid you could hold off giving credit until the 
chunk is verified OK (with info from other clients) - therefore you know they 
didn't send you fake data to abuse the system. Although a client which 
uploaded fake data on purpose would have to be a really *evil* hack of a client.
