Laurens Hoogendoorn, RIPE NCC IP resource analyst, suggested that I address
this issue on this anti-abuse mailinglist. I did so. If Laurens Hoogendoorn
cannot put the issue to the working group, I should not waste any further time.

The way it looks from my position as ordinary spam victim, it looks like RIPE
formerly had no policy at all requiring ISPs to register an abuse contact
address or to prohibit untruthful information (such as a famous ISP registered
in the country Republik Cyberbunker), and it looks like RIPE made some degree
of improvement in this policy. But if the community really still favours
spammers, I'm sorry I wasted your time too.
