There's nothing wrong with being content agnostic. We all used to upvote our friends posts by 100% and that didn't matter then, why should it matter when we let a bot give a small vote every now and then?
I don't see the reason to complain when the vote sizes never ever make anyone's post trend, or make them rich.
Also, it allocates a certain amount of votes on a weekly bases, and if the person only posts one post per week, they get a larger vote per post, than he would if he posted say 25 posts per week.
Concerning your idea about the bot voting for the most upvoted post... I don't see a reasonable way to allocate the votes to the most upvoted post if the users have different styles of creating content. Some only post one post per week, some do it more erratically. The bot needs to accomodate to that. And still it needs to be fair.
I think the way it does it now is as fair as it can possibly be, but if you have a better idea, please share.
If however there is a concern that the bot-owner will run with the sponsorships, one idea is to automate the bot via a smart contract, so that the funds will be only available to the bot and no-one else.
