These are good points, especially I like the expression perceived abuse. I haven't added any data about the issues, that is true. And it is definitely worth to investigate this much more to put bid bot promoted posts into a perspective vs. organic good content.
Thanks to @trufflepig, however, I do have some numbers at hand. So usually people spend about 15-20,000 SBD and 2000-4000 STEEM on bid bots each day. These are heavy numbers if you consider that only about 50,000 STEEM are added to the reward pool in the same amount of time.
But yes, this proposal would penalize everybody, or at least affect their voting behavior. Yet, if everybody benefits, I think this might be a worthy sacrifice.
Again, you have raised some valuable criticism, thanks! I hope this is encouraging for everybody to also point out flaws and errors in this proposal. I really appreciate this :-)
Yes, thank you for your positive perspective. I am considering adding a delegation to @trufflepig for your efforts.
Now you got me thinking about another approach to improve the blockchain, by having expert curators on given tags. They could be voted on like witnesses, and could gain influence and rewards if they provide valuable suggestions for worthwhile posts to be viewed in a combined feed of the tag they monitor.
