Interesting. I had not seen that, nor was I aware theymos actually locked the account.
I don't think it was theymos. When you change your email address, you get an email on your old address with a link to lock the account within 14 days. I'm pretty sure that's what mdayonliner used.
That makes more sense. I wouldn't expect theymos to involve himself in mday's thirst for attention.
It's just a matter of time, I'm afraid.
