Seemed important enough to make this public, I have two announcements:

1). We have been updating our payout engine to not make use of the offical bitcoin client-accounts system, which now after a time of real world operation seems unreliable. From now on we will only rely on our own accounting. We did not actually use bitcoind-accounts for real balance checks, but transactions were based on that. Long story short, as a result, some payouts today and tomorrow may become a couple of hours late due to the payment system upgrading (and thus downtime).
All balances and wallets are in check of course, just small delays on payouts.

2). Some users have been requesting payouts to invalid addresses.
Our service does of course check the address for looking valid, but not every string containing the right number of characters from the right character set and starting with "1" is a valid bitcoin address. These particular addresses were denied by the bitcoin client, and no payments were done. We have now manually reinserted the lost money into the system and routed it to the proper accounts, so your balance should be available for new payouts, but please note that we will not be checking for improper addresses in the future. It is your responsibility to provide us with proper addresses.
If you feel this is somehow our fault still, please contact us here or using the soon-to-be-done contact form in the tor service itself.
