It has been confirmed from admin that they are two different users.
I got this email from HC admin yesterday after asking if they could check the two users as I believe it could be used to manipulate the forum:
"No, they're not the same, but some may know each other. Don't worry, mods watch these things, but if ever in doubt, it's best to TOU a post rather than contact admin.
I I accept their response, but it was very suspicious.
I apologise for the public manner in which I questioned their integrity.
