The four post limit used to work "behind the scenes". You could post as much as you want, but when you have more then four per day, a penalty would get applied to your post rewards.
The penalty wasn't even really that bad for 5 or 6 posts.
It was an elegant system and it worked just fine for many months. It was removed without any real discussion or reason behind it.
Can Steemit implement it only for some users that are obviously draining reward pool?
in that regard, is there a place where all these unspoken rules are stated? The whole "upvoting rewards vs time after posting" is still a mystery to me, and seems to have changed a bit over time and I cannot find anywhere where up-to-date info exists... The 4-post rule seems like another one of those rules that I heard about a long time ago, but only through other people commenting on it...
Thanks, again, stinc, et al.
