Yes i designed all those sites
*although the work is several years old now and its slightly embarrassing to see old work.
File sharing sites..No problem with that. But that doesnt mean i support content theft. I design... for money.
It's not my job to look into the future and see what your intended purpose is with your design.
For all i know these sites may have been run legally and ethicly.
But again.. i have no crystal ball.
