I think ARIN is no party to contact all RBL's and do any cleanup of
'contaminated' address space. The only steps ARIN might do are:
- When requesting address space, one should be able to indicate whether
receiving previous used address space would be unwanted or not.
- When assigning address space, ARIN should notify receivers if it's
re-used or virgin address space.
- When address space got returned to ARIN and there is evidence of
abuse, they have to mark that address space as 'contaminated' and only
re-assign that space to new end-users who have indicated to have no
problem with that.
