1) not allocating to known offendors (even those who've been through the court system and had judgements against them, which would be following your proposed path)
[ i made no proposal. i was just a bit scared by the instant "we need to DO SOMETHING" reaction. ] but what you say seems somewhat prudent, at least leaving the judgement where it normally is.
2) dealing with rbl'd netblocks once they are returned to ARIN and the re-allocated to 'new' people.
tough one. those 'bad' blocks will seem less and less bad over time. but can we not expect the hostfolk at the rirs to kinda order the available queue on this, as well as other appropriate attributes? i.e. is this not more process than policy? i am not saying all is well here. i am just trying to move slowly and pretend to think while on my first cuppa. randy
