You better discuss issues out here than GitHub, we have more people following the forum than GitHub.
About your proposal: what is the stock value, in your opinion, that would be limiting the community connections? If we set this max. stock to 10, is it a problem? What about 100 max connections? Maybe at this last level community would have enough stock to certify individuals at the same rate they meet people in real life.
Anyway, I already answered here for example why I am against the certification revokation (aka “anti-certifications”).
I understand your reaction about the will to “answer with brute force” against attackers, you are not the first neither the last to evoke it. However you are trying to fight against a debt-money behavior (the attackers who wants to get money) that IMHO isn’t that relevant in Libre Currency. We already have experienced many times with Ğeconomicus games that money is no more the precious thing we all hardly try to obtain. Instead we focus on producing values.
