the most important drawback of these auto votes is that even if you publish a null post or shit, it get rewarded. (you must try it once)
I have screwed up a post once. I spent the next 3 hours writing a post in its place to make sure the votes weren't on nothing. Back then, I was earning far less than today.
Now with upcoming hf25 I hope people get enough time to curate and thus focus shall shift on manual curation.
I think it will make a difference.
