My dotcom 1.0 employer did exactly the same thing, although I think ours was called 'Black Box'.

If a recruiter said they had 'Black Box' candidates ready and waiting to come in for interviews we knew the recruiter would lie, cheat and steal to get candidates placed (and their fat commission cheque).

If a recruiter said they hadn't heard of Black Box but would reach out to their pool of candidates, they'd be considered a bit more trustworthy and perhaps worth doing business with.
