Well... I can say that Netload definitely do payout, but only once you've accumulated $50 worth, and they deduct I think $2 as a fee.
I received a payout from them this month, and your details need to match your PP details, otherwise they won't pay.

I've been using them for a while. The only reason I'm considering stopping to use them is that they are way to harsh in their deletion policies.
I've uploaded unique links many times, only to have them deleted after a week, even if I didn't post them ANYWHERE. I think they sometimes delete files solely based on strings in the filenames.
It's a real bummer, and I'm considering moving over to HF just because of this.

One thing I can say is that Storage.to is really crappy service and don't pay out, but their shitty service goes both ways... they very rarely take down files for copyright violations.
I'm thinking of using them as a backup site for my links.
