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.

With kind regards,
