Uploaded.to is a fine host.
I can provide many payment proof if you want later tonight. However those are done before the site revamp. I haven't got a single payout since then because i do not upload there any more - free users hate it because it offers really low download speeds and sometimes download is unstable (such complains i used to get when i used uploaded).
What about payment delay, it was random back then. Sometimes i could get a payment in few days and sometimes i had to wait for weeks (longest delay lasted for a month, not longer), however every single time they sent money.
As said poster above me uploading speeds are great.
The downside of this host is small storage (i think it used to be 30Gbs of permanent storage even for premium users if i am not mistaken), short storage time and slow download for free users.
