Hello there,
Seems there is some people in Ukraine that love to use IP and AS that doesn't belong to them.
See :

Seems that there is no AS42989 as upstream.... So we can consider that AS42989 is handle illicit activities, and does not filter prefixes (same also for AS57954).
That's cool but those people in UA, use that prefix to send spam, as LIR member I got thousands of mails from people that get thoses IP as spam source.
Needs really that rpki and other stuff to be deployed massively.
If some people from those UA AS can do their job instead of getting the honeypot of spammers, this should be better for everyone.
I have already tried to contact abuse / email from ripe data base : no MX, mailbox doesn't exist, even the domain doesn't exist...
Maybe AS-MTU doesn't lookaround the quality of their customers ? So bad...
People there that have some PI and unused AS, have a look if your ressources are not used by someone that should not use them.
