Shit posting is good for bid bots and upvote selling businesses . As long as there are shit posters that cant get exposure in any way on their own, you will always have someone buying votes.

The worse the content gets, the better off bot owners are due to a bigger pool of potential users.
There is nothing more Anti-Steem then bot and upvote services.

@themarkymark can make all the blacklists he wants but you simply cannot escape that.
Bots live from shit posting. You can have an occasional, "sure, maybe this deserves a 1000USD if it was voted for ORGANICALLY"... But it still remains that it was self upvoted. Its not really trending, it wasnt picked by the community.
There just isnt a way for bots to be used "properly" and not fail.
