I've tried asking theymos many times, I never get a response.
My hope is that since my main account has a link to my OTC profile, and I can auth through that, that I could use that as proof of account ownership
From the account recovery threads I found, it seems it is pretty hard to get theymos attention and response as it is a low priority stuff for him. The best you can do is resend the PM once in a while.
