[anti-abuse-wg] Romanian Spam Network with curious effetcs

I just realized a new spam active network. When doing some deeper checks I was really astonished. There is a huge netrange (Romania) prepared for spamming. The netrange is 176.121.24.0/21 176.121.32.0/19 Only half an hour after mails arrived I took a look at a border gateway - but it says this network has no route. There are different AS numbers within the RipeDB for these networks. The AS whois looks strange. Anyone out there who can give some hints what happens here ?
