What you say here is very true... but I would submit that we can probably split things into two primary motivations... different from the above: "Short term gain" vs. "long term growth."

Whatever someone's inclination-- bots or publishing-- if you have a short term gain approach, you tend to disregard the long term impact of your current actions... and I think that's some of what we're seeing that's devaluing Steem. Those who are focused on making some money with THIS post, to get money for tonight's pizza tend to forget (or not care?) whether their actions will result in there not BEING a place to collect more money 3 months, 3 years from now.

I happen to be a long term thinker, and my interest in protecting my investment here lies in "What can I do to ensure I can still be blogging for rewards here, three years from now?"

The "invasions" we're having are very short term oriented. So what do we do?

Personally, I believe in the value of "carrots;" ie guiding people through a rewards structure. Sot it would seem that the challenge is to adjust the rewards structure in such a way that actions creating long term value and stability are favored over those resulting in short term gain.

Let's examine "investors" for a moment. Are investors purely those who buy Steem and convert it to Steem Power? Or are they also those who simply buy Steem as an asset, without interacting with the Steemit platform? Two different cats, I think.

SO what can we do? I have seen the idea of going to a 50/50 curation publishing split floated from time to time... if "human activity" is favored over automation... it might become easier to encourage long term thinking. Bots.. are just code. They don't care.

Just thinking out loud...
