Many thanks for your comment, which gives me the possibility to explain our proposal a little bit more.

"2000 SP + 5 actors" is not meant to be a cut-off against malicious actors but to prevent too many nonsense circles to be proposed. Even more, a higher threshold could prevent good ideas from being developed.

DeCentraSteem is actually an invitation to create as many circles as you want, as long as they serve the purpose of the foundation. If a working circle doesn't serve the purpose, rule no 8 gives Steemians the possibility to stop it from doing so. If somebody would create a lot of working circles not in line with the foundations' purpose, this individual would very soon lose a lot of time in mediation procedures.

Btw: the whole logic of this kind of organisation is to focus on the positive aspects of human collaboration, trusting people than rather then setting up a "perfect" system of avoiding malicious behaviour. Sometimes the trade-off will indeed be a working circle not fully in line with the purpose for a short time.

Please compare this with the huge effort centralised systems put into their control tasks. Furthermore, their trade-off is that a large part of people dosn't identify with the system (company, administration...) they work in, since they have the feeling they are confronted with distrust all the time. This then leads to a loss in engagement and effectivity.
