Non Scam coins with ID'd DEVs:
Darkcoin
Vericoin is reversing higher with some game changing POS developments in the pipeline.
Dakcoin: a coin which loves to change the rules. Changes the rewards for mining, changes the number of total to be issued...
Vericoin: developers did a hard fork in order to roll back the chain to revert a supposed theft on MintPal.
None of these could be called scams, but they are really bad coins.
