I have aquired more information on my older brother's possible account:
If he makes an account, his username will be YOU CANT SEE THIS
There could be a possible joint account: YOU CANT SEE THIS
This possible joint account would have a weekly dispute between me and him posted on it.

If he makes this new account, I will inform all of you immediatly.

Sorry if I'm being a bit unclear now, but he's concerned that someone would take it.
