You set up too many hard rules as strong requirements. That way you already ruined UX which you tried to fix in the first place.
For example I was very surprised by HF20 RC rules. Didn't expected it when I was trying to be more active on the platform after months of being inactive. Finally I decide to leave facebook and commit more time to Steem and after some posting and commenting I got locked out. Very bad UX.
But regarding your requirements, I had some things done which doesn't fit your "strong requirements". I did it as way of exploring Steem not as malicious acts trying to get some gain. Like self voting. As newbie I didn't know that self voting is something bad to do. Why that feature is there if it is malicious thing to use it? This morning I ran on a voting bot, he commented my post and then I used it just from out of curiosity. Just to see how that works. Not to gain something. Again I was exploring. Being a full time developer, husband and dad I don't have much free time. So my content would be sharing some interesting URLs from tech, science, coding etc. I presume this wouldn't be for you high quality content. But I would like to see some interesting URLs in my feed from these subjects. That can be valuable to share. Some steemians tell me that behaviour should be done through DLike. But I don't like DLike for many reasons, main reason is that site is very slow. So I'm learning something new about Steem every day buy just exploring and trying things. Like for example posting some affiliate links. Now I'm not sure if that is also malicious thing to do.
So, it's clear that I don't fit to your strong requirements. But I'm sure that my activity can be valuable for the community. And that there are many many users like me. I'm sure that lots of those users will leave Steem when they get locked out by insufficient RCs. I will not, because I understand point of RCs and I'm willing to invest into SP. Many of those potentially good users don't. As matter of fact, I'm not interested into getting charity from you. I will buy some STEEM and convert it to SP. I planed to do that just to see if I will have more RCs. As you can see I'm exploring the platform and I want to learn more so I can some day build an app. But I'm writing this just to let you know that you maybe ruin the fun for large amount of users. And that you are preventing large amount of users to join with RCs. So if you wanted to help to newbies, your "strong requirements" shouldn't be that much strong.
