I'm prepared to alter our account creation procedures to fit within the new HF and RCs.
As larger stakeholders (there are numerous that fly under the radar) may end up abusing the RC system with spawning free accounts, I'd like to see a zero (as close to zero as possible given the calculation) there from all witnesses, at least for the initial time period (let's say until 2019). Let them burn their STEEM. We can't afford to set too high until we observe the behavior of users/stakeholders.
