We've encountered the same diligence with LVL3, especially after acquisitions where records haven't been updated yet. Although a little annoying it's quite refreshing.

Clueless or big and inattentive? AFAIK, Level3 will accept anything from me...as long as I put it in one of the IRRs the day before I plan to announce it.
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.

Do you utilize the IRR, have an as-set, and put all customer AS/CIDR's into the IRR? I've honestly never heard from LVL3 about our advertisements. Other providers have varied from just needing a web form, email, phone call, or those combined with faxed LOAs. The latter gets very annoying...but maybe it is the way it should be.

Level3 pull information from a number of sources, including RIPE where we register our routes. One of the nice things about their setup is you can query a whois interface to check the filter generation: e.g. (to pick someone else's AS-MACRO at random) whois -h filtergen.level3.net RIPE::AS-DEMON Sam
