Hi,
The last time a romanian I know checked, most of these appear to be set up with business registration that was valid at the time the netblocks were registered but mostly lapsed a year or so later.
Almost as if someone in bucharest walks into a bar, pays people there a few euro in drinking money if they will let their ID get used to register a shell company that can then register for a /16 or larger netblock.
Well, the allocations/assignments are only valid as long as the original criteria are still met. In this case it seems obvious that this is no longer the case as the entity for which they were requested no longer exists. But to be certain there has to be work done by the RIPE NCC. They can't just revoke resources because someone posted a message on a mailing list :-) Submitting this information to http://www.ripe.net/report-form seems appropriate. Cheers, Sander
