looking into sooner.

        People tend to treat things like IRR (eg: RADB, etc) as a
garbage pit you toss things into and never remove from.

      Is this a non-issue that I shouldn't worry about?  Doesn't the
quality of this data effect Origin Validation efforts?

        Yes it does.  This has a fairly severe impact for those that build
off the IRR data for filters.  We have seen customers end up including
AS7018 in their AS-SET or as you noticed have other legacy routes appear.


      Sorry that this turned out so long; I wanted to give some
context.

        No worries.  I've got a transient routing leak detector
that does find/fuzz these issues which has been running for a few
years now.  I'm guessing you may see some of the related prefixes
there as a result.  It's in need of a U/I redesign (code welcome)
but is located here:
