As easy as a black and white answer would be here, I wonder whether it's more complex than that. Not curating posts would be akin to telling people that they're not worth anything, but to curate posts of minimal effort is to reward, and thus promote, posts that are likely thrown together in a rush and then published carelessly.
Having said that, I don't think a post that is 100% copied and pasted, regardless of referencing, should be rewarded. Despite the fact that references are an admission that the work is not that of the post author, if they copied and pasted, they didn't really do anything worth recognising. It doesn't seem fair to people who go to painstaking lengths to create original content. Perhaps just a positive comment acknowledging the post would be more appropriate?
Given that this is the FreeCompliments Community, that's actually a very clever and appropriate solution! It would be exactly in line with our mission. This is why I love gathering people's various ideas. Love this.
