I don't think, it will be easy to track how the votes are used, possibly someone can create multiple accounts to avoid self voting. So that's still the same.
The long term solution would be the whales and all curators curate great content , with a common channel, where the authors could reach them. That will prompt people to write original content and also be assured they get rewarded.
This will still not stop the abuse, but at least keep good people on the platform and giving them more values. With time, hopefully the good will win over the evil.
And your idea of more curation, would attract the curators, to curate good content.
