At first, I thought some of the bots that posted to threads I created were cool but they've certainly started getting on my nerves. There's one that ranks the readability of your post which is a neat idea (until it starts comparing you to Mitt Romney lol) but it isn't accurate and posts instantly to threads (alongside a couple instant-comment bots which just say "thanks, upvoted").
What do you think of comment captchas for low steem power users?
It seems to me it is worth entering not only for commenting but also for vote, vote by and large is microtransaction, to it costs belongs more seriously. I like the idea stated in this article: https://steemit.com/steemit/@desmonid/idea-to-reduce-potential-for-bots
