You won't get a response instantly, be patient theymos is a busy person and has a life outside of the forum too. When my account got hacked it took a month to get it recovered, be patient and follow what hilariousetc has mentioned.
I'm a newbie in this bitcointalk forum and i had made this account two days ago. But, why my post being deleted by admin? Did i do something wrong? I have lost my activity because of that. And also my another account has been banned by admin and i can't get it anymore.
Most likely you have posted suspicious links in your signature or your posts which has caused the mods to delete your posts. Also opening multiple accounts isn't considered a good behavior.
