[anti-abuse-wg] Allocation of number resources

Assume for the moment that there exists a provider, within the RIPE
region, that has been allocated a sizeable IPv4 block.  Let's say a
/17, just for the sake of argument.  Assume that this allocation was
made to the provider, by RIPE NCC, some long time ago... Let's say
early 2011.

I would like to know the following things.  If someone can answer
these questions, please do:

(1)  What would have been the requirements, at that time (early 2011)
that the provider would have had to meet in order to be allocated the
/17 in question by RIPE NCC staff?  (In the ARIN region, for IPv4
allocations there has been for some time various requirements in place
that say that the provider being issued the address block must have
some certain amount of hardware infrastructure in place in order to
qualify for the allocation.  Does RIPE have any similar rules?  If
so, then what are the rules, when did they go into effect, and what
exactly does RIPE NCC staff do in order to actually enforce those
rules, i.e. _prior_ to awarding an allocation to a given provider?)

(2)  If there are indeed requirements along the lines above, then are
those requirements only in effect during and at the time of the initial
allocation?  Or is the provider who has been awarded an alloction either
asked or required to maintain some certain amount of hardware infra-
structure corresponding to the IPv4 address block allocation that it was
awarded?

(3) If there are indeed ``maintenance'' requirements along the lines
in (2) above, then has there ever been a single publically documented
instance in which a provider's failure to maintain the minimum required
hardware infrastructure dedicated to some given IP address block allocation
has caused the RIPE NCC to actually revoke the address block allocation
in question?
