Presumably because I posted in the pool's topic once, I got the following PM:
Hello,
This is an important message to all BitcoinOxygen miners. We've discovered an error in the way we have been calculating payments for miners for the past few weeks. Many of our miners have been overpaid, therefore we have corrected the balances on the accounts affected. We will be accepting all losses on balances that have already been paid out.
You can check your current balance by logging into your account at http://btc-oxygen.com or if you have any questions or concerns you can contact us via PM here or email support@btc-oxygen.com
We apologize for any inconviences this may have caused.
Regards,
BitcoinOxygen

The link, just like the link in the user's signature points to btc-oxygen.com, while the real pool's address is btcoxygen.com.
After somebody pointed this out in the pool's official thread here, BTCOxygen locked the thread.
