A lot of people complain about the Trending page because it contains a lot of crap that is only there because of paid bot upvotes. I don't think most people mind if you paid for a bot upvote if you produce good stuff, but some posts definitely shouldn't be there.
Since all of the accounts of paid upvote bots are public knowledge, it shouldn't be too difficult to just make a list of those accounts and exclude any post that has used them from the Trending page. And maybe move those posts to the Promoted page. Or create another page called Naturally Trending or Organically Trending or Actually Trending or something where people can find all the posts that haven't been paid for.
Of course, somebody will make a new bot that isn't on the list. And of course it then gets added to the list. And of course somebody comes up with another bot scheme that circumvents the system. And then that gets dealt with as well.
While we're at it, let's change the names of the pages as well, to something more in line with the Steem theme, like Cool instead of New, Hot can stay Hot, Boiling is Trending with paid bot upvotes plus Promoted posts, and Steeming is Trending without any promotion.
