I am troubled by the new members joining RIPE purely to obtain IPv4 address space.
Perhaps (shields up!) RIPE could simply offer /22 for purchase at the same price as membership (€3,400 i.e. joining fee + 1 year subs) to anyone who wants one since they can get one anyway by joining.
It would save the admin overheads and would identify members as those actually committed to performing as LIRs.
I can't imagine this will be a popular suggestion, I'm just putting it out there.
