Managers are mostly responsible for such posting. For example, even yahoo, sylon and other worthy managers wants from their bounty members 20+ posts per week. It's not easy to create 20 worthy posts.
If it's difficult, then don't apply. Is that not a simple principle to follow?
It's not easy to be a full-stack developer with minor programming experience. Campaign managers should take responsibility, yes. However, at the end of the day, if the campaign member is not sufficiently qualified then they should be booted out. Furthermore, they shouldn't have applied in the first place. If all that they can output is bad quality work, then that's not something that should be rewarded.
TL;DR: You should not be paid for a job you cannot do.
