"Outsiders can't just create REP in a minute and take the whole chain (like Justin Sun suckpuppets did). If STEEM had a REDPOS protocol, he would at least needed to start a "stealth" attack first (create the suckpuppets and "work" on them to adquire enough REP to guarantee a good witness rank)."

Actually, with the stake Sun has, he could quickly buy the highest rep on the platform from vote sellers, in only a day or two. At least the way Steem rep is now.

The account age is also not foolproof, although it's better. I just found an acount this last week that has been here since 2016 but made it's first comment that day. They've been delegating to bots during their entire tenure on Steem, but not socializing at all.

While this is an outlier account, and it's pretty hard to imagine anyone setting up an account and waiting for years for it to be usable for some kind of illicit attack on governance, I also know of users that have claimed to have ~10k accounts, and presumably have simply been adding accounts since they got here, and got here early. I am pretty sure there are a lot of users with a lot of accounts, although 10k is, again, an outlier.

Because there are so many of these 'pre-aged' accounts, I don't think account age is a functional rep mechanism we can count on much either, although it might be very useful to look at account youth with suspicion instead.

I do appreciate your interesting ideas, and don't want to discourage you from having good ideas, but do think the criticisms I've brought to your attention should prompt you to think more, and have even better ideas. One of the problems with society is how rep works IRL, and that's why we get such shitty politicians in office.

Pretty sure I don't want the same combination of self-aggrandizing psychopaths with piles of money buying their way to power over Steem. Oh wait..

Anyway, I hope I didn't communicate that I have no interest or respect for this concept. I do think it's incomplete as I have understood it. I do think it can be better than DPoS, at least the bungled interpretation of DPoS we have atm, but I think rep needs to be improved before it can be used to decentralize governance in the way you want to use it.

Thanks!
