Coins I've looked into that seem to have some red flags:
Feel free to argue why i might be wrong on these, I have not completely researched them all. I tend to be risk averse and avoid coins where the Devs might dump a large share, but still want to get in early.
SPARKS
LUX
Lemanum
MUNcoin
BULWARK
Mostly shitcoin clones made to dump premine into fools hands. (LUX can be an exeption, and may be BWK)
