I just got word from coreintegration on the matter of their acceptance policy on new members.
They do indeed perform a screening in so far that they want all registrations being properly filled in, especially getting correct names and mail-id's. Since they have to make a living, they want to make sure that the core is not used by the competition for profit sake. Students are allowed to participate if they register as such.
I have no opinion on this, perhaps you should contact them to resolve this matter....
