The basic conclusion of this video was, every big account used a bot at one point in time, especially in the beginning, and a decent percentage of accounts, even those with more then 100,000 followers, still use bots to increase their likes and comments.
If we look at other big social media sites, there are bots. Reddit, Youtube, Facebook, Twitter, Quora, MySpace, it doesn't matter, bot's are relatively easy to code, and hard to get rid of.
Think about how easy it is to create a new Reddit account. 10 Seconds your done, not even an E-Mail address is required. Now copy the code of some Youtube tutorial of a 12 year old and you have your own Reddit bot up and running in 10 minutes.
 and their non transparency regarding user votes, it can be incredibly hard to differentiate between real users and bots. You want to know who up-voted a Reddit post? Well, if you don't have a snapshot of every user profile and a supercomputer at hand, it's not really possible to find that out.
On the other hand, here on Steemit you can see the biggest voters with a single click and although you won't get a detailed statistic of bought votes vs non-bought votes, you get a general idea on the usage of bots on that post.
