What is your most favourite bot on Steemit and why ?

I know the Platform allows it, but I'm not a big fan of using Bots to get upvotes. It's just my humble opinion, but it seems to cheapen the experience. I guess it's not a lot different than a promoted post on twitter, facebook, or Steemit for that matter, but at least on those, it shows as a promoted post.
If I had to pick one it would probably be Build a whale Hive account@buildawhale , they seem to take the spam/junk posts pretty seriously and blacklist some users.
There are some other Bots on the platform but bid bots seem to be the hot topic.
