This post and all the incredibly engaging comments on it has now become my go-to reference whenever I find any talk on bots/buy-services being good or bad. Thank you. I'm also now voting for you as witness, for what it's worth ;P
I disagree with only one thing you say in your video: That this only really applies to the bigger fish and that minnows using bots, etc, won't really affect anything.
Of course it's true that a single minnow doing so has a negligible effect, but isn't it like polluting? One person throwing throw a piece of plastic into the ocean isn't going to affect anything, but let millions do so, and we have a big problem.
As far as I know, only 1% of Steemit users have over 100SP. Surely it is a good idea to encourage the other 99% to use the platform responsibly (and as you point out, self-beneficially in the long-term)?
