Combination of Self-Evaluated & Auto-Adjusting Limits
@inertia posted the following More Max Payouts = Less Bot Impact
This act would not only encourage people to support your post, knowing that there is no chance it will skyrocket unjustifiably, but also it would greatly aid in maintaining a healthy rewards pool. People appreciate when someone says, hey .. this is not my genius, I'm sharing someone else's, so maybe throw me a few bits for the effort ..
When such a limit is placed by the author, it should be noted in the post as a UI function .. so that people will not waste votes after the maximum is reached (either that or make a change to the code where additional votes would not negatively impact the supporters curation power).
Taking this all a MASSIVE STEP FURTHER .. would it not be wise to have an automatically adjusting, STEEMwide maximum reward, based on the current health of the rewards pool? Mmmm.. something to think about! All of this combined would make flagging-to-reduce-rewards entirely unnecessary (which I believe was a point that @inertia had made in his article).
