I completely share the ninja mine view of darkcoin, and it puts it for me in the category of very dishonest coins, to be polite. But apparently it's hard to claim that without entering in arguments about numbers, dates, past posts, etc. with DRK holders.
I personally prefer to say that the technology behind DRK is limited. It is a pre-historic attempt at a privacy-enhanced cryptocurrency, where cryptonote is the 21th century. This is enough for me no to be interested in DRK regardless of the initial coin distribution, without entering in endless justifications of "why premined", "why not premined". Stick to the fundamentals of the coins. This already discredites DRK completely and these are facts that are much harder to arg on.
