have you checked the files with bitzi ?

it is not about the people , people know that a lot of searching or detecting p2p clients come from the states or there own country.

so people block them " states" or special bloacklist for mediasense like company's..

still if you find an file and you can not download , and you check the file with BITZI, and sources dissapear , wel maybe something is wrong with your ip adres

otherwise i dont know why you loose so fast some or all your sources ..........
