Just take a look at the mess in /r/storj. Farmers are unhappy that a large portion of the payout seems to be going to people either cheating the system entirely by generating traffic pointed only to their node, or breaking the rules and having multiple payout addresses so they can have tons of farmers getting the minimum payout. The moderator Helmex:

As long as Storj keeps paying the farmers more per downloadedbyte for bandwidth than the renter is paying for downloading their files, there will be people taking advantage of this situation.

It seems like these issues are technically fixable, but there's still a huge problem with communication between farmers and the Storj team.

There's also been some confusion/drama because people have been changing positions at Storj. Again, it's 90% communication problem with farmers.
