not all do.
I was informed I was put on a whale's bot list, after having demonstrated producing consistent quality / well-rewarded posts. This article from @infovore is an interview with the investor/bot owner that breaks it down. This is another article by the same investor where he puts out a request for writers.
The bot doesn't vote on ALL posts though. The last two before this never got the votes - so there's gotta be other criteria programmed into the bot - it must only be looking for articles from certain authors that match specific qualifications. I don't know what those criteria are (yet)...
