There's a flaw in the way the Bitcoin protocol distributes objects which can be used cause mischief with a PoS (and hybrid PoS/PoW) coin that has low PoS difficulty. I won't go into further detail, other than to say I have discussed it at length with Sunny King and for a popular coin like PPC is unlikely to be possible, but for the quieter coins it is of more concern. I can't see any easy way to fix it.
If trouble awaits with certain kinds of coins, it would be nice to be informed about it. Don't you think serious hackers who perform real attacks are far more likely to already know or be able to figure it out on their own than normal users/investors, and hence giving more information about it here is more likely to benefit normal users than real attackers?
I agree with your sentiment, but in practice if there is no possible fix (or way to protect yourself) then revealing details will just accelerate the 'mischief.' As mentioned I have discussed it with Sunny King but I think he's more concerned about looking after his own coin, and PPC currently has sufficient strength for it to be an irrelevant issue. In hindsight, I probably shouldn't have posted anything at all.
