You might be on to something here. Banning bots would make Steemit more organic, but, being new here you have to realize that for most Steemians, Steemit is about amassing tokens, no matter what other rhetoric you may read here. It's a game. The one with the most points wins. The devs are not about to ban bots.
I personally don't have a problem with bots, but I think a bot that misrepresents itself as a human is committing fraud. Steemit does use a lot of bots, but many of them are known and declare their bot-ness. That's good because I won't waste a lot of time answering some algorithm-generated, generic comment. When AI gets to the point of reasoning, then I'll be happy to monkey wrench its CPU via the written word.
Perhaps Steemit should consider some form of bot tag, some symbol next to the avatar that differentiates a machine from an organism, or perhaps a bot registry that we posters could access like the drop-down vote window that lets us see who upvoted our posts and comments. That would create a bit more transparency on this blogging platform and may be a way to entice other bloggers to abandon their fraudulent, commercial blogging platforms and join the Steem Teem.
