A trusted node in SolidCoin is a node which has a significant amount of SolidCoins (at least one million) in a special account. This account is used to "sign" a trusted transaction block to say that this person with a lot invested in SolidCoin agrees with the previous block.
But the 10 accounts that have 1.2M coins have unspendable coins. There is no investment. Nothing to lose (other than control). If there ever was another account that had 1M coins that were actually spendable, then that huge investment is dwarfed by the out-of-thin-air coins. So, SC's reasoning doesn't make sense. By allowing these fake coins to make a node trusted, he has broken his own system.
