Seems that you misunderstood him, Paypal BANNED adult content, that's why you don't see legal adult websites with paypal payments options, and if they keep going with their really strict policies they could ban the purchase of domains for adult websites, or sex toy for an example, and the law has nothing to do with this.
Now going back on topic, i'm the collateral damage, i'm not a pirate and i use file lockers to share pornographyc drawings that I DID, but now seems like this "freelancing job" it's over since the only way to get the money over here is with paypal, and at this rate filelockers will ban adult content at all, anyways i will find another way to get few extra bucks, but i loved file lockers due their hight pay rates.
