You can send him messages I bet. I doubt he has it automated. What ever you type in as a mnemonic he will read it.
The last two or three times that I used mymonero.com, it wasn't syncing. It would say your account is 10 blocks (or whatever) behind. Then the number of blocks behind stated by the error message would increase gradually.. So in effect it was frozen. Something was probably interfering with my connection to mymonero.com, preventing communication. That could be what made it look like the blockchain wasn't syncing. If there was a man-in-the-middle attack, maybe that would explain the lack of a connection, I don't know.
It would be good to figure out what happened, if not for my sake then to prevent it happening to others.
Fluffypony said in his response to my support email that the server has not been compromised. I don't think I can ask or expect him to spend much time on this. Maybe there are people with some expertise here who are more interested.
Very sorry to hear of your loss birr. That thing with saying your MyMonero account is behind has been happening for a few weeks that I know of. It also happens to those not using either VPN or Tor.
