Thanks for this. Just resteemed. I hope that in addition to what you specified above as being ongoing work on this current HF, you're also continuing to consider some changes to what unfolds with RCs/mana in the coming week(s).
The more I dig into it, the more concerned I am that efforts to thwart spam may have resulted in RC calculations that actually thwart new users, whether spammers or genuine content creators.
If the calibration going on shakes out to where it really does take 7.5 SP to post or comment once within a 5 day period, well I hope there is a plan to do something other than just accepting that and rolling forward with it.
