putting much work into it.
In terms of how many coins are generated early, PPCoin is much bigger scam than Litecoin.
I don't consider PPCoin or LTC a scam. I think you have to separate SCAM coins from simply Poorly designed coins. Any coin can have a poor implementation, diff, block reward etc. What makes a SCAM coin (Bitbar, Mincoin etc.) is that they are designed with the sole purpose of making the developers and their 'friends' rich.
Signs of a scamcoin:
Launched at non-peak forum hours with no, little or faulty launch time.
Convoluted design for the purpose of discouraging public mining in early blocks.
Quickly dropping block reward to reward 'prepared' miners (aka. inner circle)
Very low starting difficulty that quickly increase (also to reward inner circle and pre/instaminers)
Ultra fast time to market. aka. Appears on trading solutions within a few days. To enable early miners fast and profitable exit.
LOTS of forum PR (spamming altcoin forums)
