Before you spend your precious time, beware of 2010 Bux. They advertise instant payments and have a forum. This shows payment "proof" of members, but there is no "reply" available in that part of the forum, so you can't ask the members if their proofs are correct.
I requested a payment on 24 May 2012, sent support tickets and posted on the Forum when it was late, but I haven't heard from Admin at all.
I believe that 2010 - Bux is a SCAM SITE.
