Perhaps there could be both - an initial 7 day payout and then an ongoing 30 day payout for posts. Best of both worlds :)
abuse point is difficult - it's like there will be bad actors until there isn't. I think a lot of that over time will be less and less - I think part of the issue with abuse is a result of our individual attitudes and relationships with ourselves and each other. I mean if we just look at how money has been created historically...it's been through war/violence....the war machine. So - we've got a serious paradigm shift here as a real tangible social experiment that is happening - I think it's possible for the nature of the human to improve for the better....and I think moving forward, perhaps with the creation of SMT's and also EOS - we will be able to create added support systems/structures to prevent and limit abuse.
