Don't really know what you want to know, but anyone is free to stake their address in the official thread, so in case your accounts get hacked, you can sign a message from that address in order to recover your account here in bitcointalk.
True, but the recovering procedure is not working : even if you show the proof that you own the account with a signed message related to ID PM messages and thread posts, none of the moderators (Theymos or Cyrus) are replying.
Personally, I never saw someone who got an answer and recovered his account back.
