I got 200 emails from them saying:
" Hellooooo, potential holiday maker!
Unfortunatly the username jamesm87 that you asked for has been made forbidden so yours and others reservation for this has now been deleted. But need not worry, you can goto http://www.clubtropica.com and reserve another funky username instead!
Sometimes ClubTropica makes names forbidden if they breach any terms and conditions we may have, or if they are offensive or the potential to confuse users.
Hope to see you soon on the flight!"!
Urgh.
