here my suggestion to you:
1. please add waiting time after one download to free user, example 15 minutes, if not you hard get premium sell
2. remove ranking systems and add Pay-Per-Download-Per-Country
Welcome to WJ
but according to my experience with Uploading.com is very bad
1. after payment they decreased users rank to low level.......
2. They hold users payment and ask users to show Forums/blog where they share uploading links but this processes takes upto 15 Day which is very Bad and users hate these things
I have pain with this file host also. After first payment they decreased my rank to Light.
Second payment, they asked me to show Forums/blog where I share uploading link. I have supported them all but after eight days, they didn't do anything. I asked them again to send money for me but they continues disturbing me and payment still was declined.
Now I still have 70$ in uploading account and they didn't send for me , They are very terrible file host and staff worked unprofessional.
Need more of your comments to know that this file host was scam!

you can know that from her http://uploading.com/contactus/tread/196530/
