For your 90% PPD question, I have explained them there. 10% is off due paymeny processing fees (which is a lot!). coming to your adf.ly comment, do you know that members are earning close to $100+ per day at filedownloads.org (in total)? So how do you expect to keep generating revenue to pay you guys? Also, do you any any idea how it costs to host a file host with even okay download/upload speeds. So we have to put up alls those ads just so that we can remain profitable and be able to pay our good affiliates.
Too much "Do you know", i guess it's now my turn,

Do you know, that there are alot of other successful filehosts admins who didnt do that at their start ?
