Edit: This is for Coinye coins only. I did not process GPC or CKC coins yet. I want to get these taken care of first. I intend to bring the other two pools back online later next week.
As a pool OP myself, I still don't understand why you are requesting people to contact you. You have a DB record of what people are owed. You have the ability to move the wallet.dat file to another computer to manually do payouts. By now, the DDOS script kiddies are long gone and on to the next target. Turn the server back on and either move the info onto another computer to manually do transactions, or start the server back up and let it process them by itself. Even if the user didn't have the wallet address listed in their account, you have their email address and you can contact them for it. Going the extra step to clear your name would go a long way, instead of leaving people hanging and still wondering where their coins are.
However... if people were mining and you're saying that they have a zero balance, and they are saying they should have coins... well you need to straighten that out. Whether you're saying that the coins are lost, or you're able to undeniably prove they have no coins. Stratum logs would show what they submitted, and when. Cronjob logs would show what was paid out, and when. If the two don't match up, you're going to hear a lot of accusations still, and you might want to just give up on the ideas of running a pool.
Either way, you can do yourself a favor and post a screenshot of the server wallet balance, and then post another with the transaction log when you get the balance as close to zero as possible. This would go a long way for your credibility. This and providing copies of all the logs to anyone that requests them... specifically the cronjob logs and the stratum logs.
Just being honest, and trying to help you out.

If someone was told they have no coins, post your username here so I can publicly post your transaction log. Thanks.
I have been mining at your pool for several hours with 1000kh/s and you are telling me my balance is zero? I had confirmed and unconfirmed balances in thousands of COYE before you turned off your server !! I am still patient
