If Google supects fraudulent activity, bans the account and then refunds the advertisers for this period of time, then it is logical that since there is no ad revenue they can't pay out any funds.
If they keep the money for themselves - don't return it to the advertisers and don't share it with the Adsense publisher - then - at least where I live - this is called fraud.
Because if there was no suspicious activity in that period of time, they have no right to withold any money. If you have not broken the contract they don't have any right to ban you or withold your funds. And if there was suspicious activity and they simply keep the money - then they are defrauding their advertisers.
Why not contact the advertisers and find out if they have received a refund. As an Adwords advertiser I would be very eager to know if Google just keeps my money in cases like this. However I would be surprised if they did this. Because if this was an official business policy this would be a very serious criminal offense.
