Well, one or the other is a sock puppet, as I've said before, Captian_Brown claimed on WP to be an 11 year old girl named Emily.
I'm not sure I understand what you mean. As far as I can tell Slim is the username the member uses on WP, whilst Captain brown is the user name they use on here.
The IPs of all new members are checked and any of those who already have accounts are labelled sock puppet.
If slim claims to be 11, it is possible that someone has gotten their wires crossed about this-captain brown doesnt post like an 11 year old kid, but perhaps it should be checked out.
