Its possible to avoid paying insurance in the following way:
The insurance rates are 0 now and no-one pays insurance. The gas costs relative to the insurance costs + the flash loan fees determine if this is an economically viable attack. Otherwise it is still a grief attack.
This will probably be detected pretty soon because the insurance pool will stay empty. However its difficult to prevent.
See issue page for code referenced in proof of concept.
Recommend setting a timelock on withdrawing insurance.
