so you want to take this route, huh? ok, let me break it down for you...
every last thing i sell on ebay is legal. i don't bootleg even though i could make a few grand in less than a week by selling unleaked boots. do i do that? nope. next?
while i agree with rukas that the concept of your site is noble, forcing people to register to download is the same as me spamming the board to come join maverick's site. if you allowed direct download links, then great, but making people register is just wack. that's the reason why half the remix entries never got listened to. you have to register for lulu? nope. not if you know what you're doing.
when it comes down to it, either you offer links that someone doesn't have to journey off the board into the bowels of some other site (spam) or you provide links that can be downloaded either directly (lulu or private hosting) or through a couple clicks (rapidshare, youshareit, yousendit). we both know where ********* lies.
don't try to school me. there have been dozens before you and there will be dozens after. the thing is that they'll all be wrong.
