I actually like isaac.asimov bot, he's useful. Not sure why he's being targeted for downvoting.

I agree that Steemit is starting to look like the battle of the bots. I don't really agree with the preventing bot upvotes and comments with human verification tasks. These can be circumvented simply by paying a human to solve them if not by other means. It will just become a case of he who has the most money and/or can last the longest wins and will still profit.

I think a better approach would be finding a way to make it less profitable for bots that are not contributing to the development of the community. With comments that is fairly easy, just downvote the comment.

The much harder problem to solve will be bot voting. The antispam (Not going to add the @ because it might decide to look my way, lol) bot has even targeted some users posts that are obviously original.
