Right, but the problem also exists globally. You have (re)discovered a
problem that is widely recognised.

Yes, this tool already exists. It is called "RPKI" - I am not joking. I
hope the Brazilian community soon gets access to it, because this is
where everyone is heading.

Why are you shaming me Douglas? I work for an IRR, it is my job to help
maintain the NTTCOM database. We have recognised the flaw and concluded
that the solution is to let RPKI data supersede IRR data (when there is
a conflict). We are investing significant money to resolve the issue we
(as IRRs) are part of. What more do you want me to do?

I already shared with this list what real actions we are taking, what is
already happening in other regions to help reduce this problem. If the
follow up is "well, i'm going to ignore your solution and still want to
shame you"... I am not sure how productive that is :-)

We are going to follow slightly different heuristics, because those are
more widely deployable. 

What seems to be the essence of the problem here is that operators in
Brazil don't have access to RPKI services yet. I think almost everything
you highlight will be much easier and simpler to deal with once BR
operators can publish RPKI ROAs for BR prefixes...

Kind regards,
