We have at no point ever operated an exit node. We may or may not be operating a relay. Our system keeps no records of deposits or withdraws, only a balance, even if someone gained access to our hidden server there is no way they could link past deposits and withdraws, only ones in the future.
Even if you just ran it as a middle-relay. You admited you ran it and you admited it went down on a specific date with an aproximate hour. That was not a smart thing to do.
Next time your server goes down, keep the reason to yourself.

We just experienced about an hour of down time. We thought it would be a good idea to configure Tor as a relay to increase security, but it used up all the ram on the server and we had to reboot it.
Please do not worry if you had deposits. We are here for the long term.
