vBulletin: what happens on aMember product expiry

Hi

Let's say you have a vBulletin (4) usergroup which can have signatures and blogs if they have product A in aMember.
What happens when the product expires and is not renewed? Do all signatures and blogs disappear?
And what happens if the aMember user re-activates product A two weeks later? Will all the signatures and blogs re-appear automatically?

Thanks

Thanks Alex
