Working for a company that has been steadily growing through
acquisition, we have actually run into this problem a couple times
before. I'm not sure if we hit the lottery, but our upstream providers
(including LVL3) have definitely intervened when we've moved netblocks
from a company that doesn't match our name into our facilities to be
advertised under our ASNs. I'm not sure how diligent or widespread the
validation checks are, but at least on occasion they do occur.
