I've just read this on netload web page :

"Every user start with $25 USD per 20,000 points.
The earning adapt to the quality of your downloads and can rise up to $100 USD or drop down to $10 USD. You can check your current earnings in your account.
The quality of your files is particularly depending of the file size, the produced advertising and sold premium accounts. (Tip! 100Mb files have the best file size)."

So this means that it's a kind of rank system : you can reach the 20.000=100$ only if your account brings them a certain amount of premium accounts sold....I don't like very much hoster with rank system However my downloaders are very bored to download from hoster with chaptchas so I've absolutely to find an alternative to filesonic and for this reason I've to consider also Netload even if I don't like rank system
