Oh come on.  Most of these people are just renting hash to mine coins.  They don't know how to look at code.  They might run the wallet through virustotal but that's about it.  A 10% premine isn't something that you just forget to mention.  If I hadn't looked at the code, found the 10% premine, and posted about it, when were you going to let people know about it?  Do you think it doesn't matter that you took a 10% premine and then just neglected to inform people when you launched the coin?  I would bet that if you had mentioned the 10% premine in the ANN that nobody would have mined the coin.  Now they've mined it and it will never be worth anything.  You've wasted peoples time, money, and resources.  You should have given people the option to decide if they wanted to mine a 10% premined coin.  What you did was wrong.
