2001:590::/32 _is_ being announced by both AS4436 *and* AS4474. Trying to contact these ASN's to inquire why that is happening and maybe finding out if it was an erronous configuration I tried to find the contacts which lead to AS4474 not having any contact information available per ARIN registry. Thus who do you call then when AS4436 doesn't seem home? Indeed: ARIN, which also didn't seem home thus: NANOG.
Next time you want to contact a noc, you might want to try not doing it as a cc: to an e-mail encouraging random peers to depeer someone because of an inconsistant origin AS caused by the use of local-as.
I wonder why many people are acting so hard about that small mention of it, apparently that did take enough attention while the subject at hand didn't get taken a look at at all. For your pleasure below is the complete detailed message I sent to them. If you still think that I am a 'kook' or other odd insults then please keep them to yourself. I thought NANOG was for Network Operators and not for flame wars and tidbits.
Actions like that (and these for that matter) tend to get one branded a net kook... And feedings the kooks is never productive. :)
Thank you very much for yet another insult, at least you are polite enough to do it on a public mailinglist instead of trying to mailbomb me. I still wonder why that is happening as I was and still am trying to be friendly and hoping to figure out why it is happening. FYI there are only 2 prefixes that have this currently in the entire routing table but alas.

AS4474 information is apparently invalid according to ARIN whois, thus emailing their 'upstream' AS4716/Powerdcom (admin@pwd.ad.jp).
From grh.sixxs.net, see http://www.sixxs.net/tools/grh/ or directly: http://www.sixxs.net/tools/grh/lg/?find=2001:590::/32, see formatted output below.
It might be interresting for you to setup a peering with GRH so these bugs are better traceable and we can easily see that they are or are not originating from your systems.
