market and is "selling" ASNs to whomever is interested and facilitates
allocations of PI netblocks to those who can justify them. It might
come as a surprise to you, but in Romania there are a lot of companies
(even very small ones) with their own ASN and PI netblocks. This setup
makes it extremely easy to switch ISPs with virtually no impact on
network operations.

If I'm not mistaken, companies use Netvision for cheap internet
access. GTS is more expensive, but theoretically is providing high
quality internet access with good SLAs.

from all those websites it looks like they are all hosting companies.
have you tried calling the numbers listed on the WHOIS registrant
information on the ASN and you couldn't get to any one ?

If you really believe that all those ASNs listed by you above are only
used to host spammers, then by all means please contact
alerts at - that is the Romanian CERT as they are active and
will investigate the allegations you make.

So far I do not know a single web hosting company that it's customers
never spammed anyone :)
