If you look at these sites, almost every article is bashing some coin, then the coins they DO PROMOTE, happen to have the exact same attributes, or worse, as the coins they claim are scams.
Take Cryptocurrency Times and it's Darkcoin article:
http://www.usacryptocoins.com/thecryptocurrencytimes/uncategorized/dark-coin-a-valuable-new-cryptocurrency-with-completely-anonymous-transactions/After spamming a million articles calling everything a scam, they magically give Darkcoin a pass and don't mention ANY of the suspcious or damning facts about it's launch.
Most of the Darkcoin issues are talked about in this guy's post titled "SCAM Darkcoin instamine 2 millions DRKs (50% of darkcoin in circulation)":
http://bitcointalk.org/index.php?topic=560138.0Darkcoin is one of the shadiest coins out there for launch and distribution. Seriously, how does a coin where blocks are erroneously set to 500 instead of 50 even survive at all? This is something that the GPUcoin dev did, and he failed like 5 launches, then just aborted the blockchain because he knew there was no point.
It's complete batshit crazy that sites like that exist and try to act as information gatekeepers telling you a coin with a 0.5% premine is a scam, then giving Darkcoin a pass with like a 50% premine.
