I agree, although I'm currently on a few curation trails to spread my vote around (though with a fairly low percentage). Also it adds weight to a few curation projects that I trust to curate. Besides that I am manually voting so far.

In terms of the layers abuse I don't consider handling automatic voting for people you support as a top priority. Especially since it distributes the rewards more widely than not anywho.

The other point is some people auto vote to send rewards back to the author as much as possible. (Early curation window). I suppose it really is on us to audit these continuously though.
