That would be like working hard for a whole day and sharing the pay with thousands of other people...
I would prefer to share a huge cake with others instead to have a very small cake for myself alone.
You can't expect most people sacrifice their time and effort mostly for the benefit of others like that.
Again, if their behaviour contributed to a higher STEEM price, and if they have a lot of STEEM, I couldn't see a sacrifice at all.
As I said, I consider myself as investor, as well, I have earned quite some STEEM within the last one and a half year ... and the value of my account has decreased a lot at the same time: the size of the cake matters, not one's percentage of the cake.
As long as a form of PoB is practiced with STEEM, SBD and Vests, it would be in the best interests of Steemit, Inc as the largest stakeholder to help the community fight abusive maximisers and non-economic abusers who harass community members for their personal gratification.
I plead for a committee of elected users with some delegated Steem power from Steemit, Inc., which could decide which stuff to flag and also (in case someone complains) if flags are justified or not, and if "yes" just counter them with upvotes.
In addition, accounts who repeatedly misuse flags in an abusive way (instead using them against spam, plagiarism etc.) could be flagged, as well, after a decision of that committee.
