There is no common similarity except what said same market, same account. If this is auto penalty due to buggy filter implementation then I am sure they will return soon, max within months. If this is manual penalty then nothing to do, these sites made million dollars since adsense released and still can run their staffs, servers and we will adapt. We are grateful to adsense, google, internet, computer.
