Considering there is money involved, I see potential risk unless the system has a way to tackle it.
We don't support it but we are only the client/protocol - therefore, we don't control what people will share. Any 2 peers can share any files and exchange UFR via the built-in smart contracts.
There will be ways for the community and UFR holders to regulate some of the content in case any inappropriate or copyrighted material is seeded. Some of the details of how this will work can be found in the Whitepaper.
Here was the reply from Dev's on piracy/copyrights.
I would like to add that any concern regarding copyright within a system like Upfiring is very similar to criminal activity within the Bitcoin network. It will be difficult to fight in both cases, and ultimately it's always the case that any largely good system comes with some small evil.
