RE: Repeated Blacklisting / IP reputation, replaced by registered use

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.
