Thanks for bumping this back up to the top of the list - I totally

I disagree, for the same reason that I disagreed when Nathalie asked
about the RIPE case.

Afrinic is a network operator. Network operators should drop ROV
Invalids. Full stop.

We're not suggesting that Afrinic should accept routes for 10/8, right?

Intelligence gathering in the DFZ has requirements that are totally
orthogonal to the requirements of a network that actually forwards
This is what route-views and RIS are there for. If we want (and we do)
better visibility into the DFZ in our region (including, seeing Invalids
and who is carrying them) then we should focus on improving collector
deployment on the continent.

AIRS is a welcome initiative. I am looking forward to it being more than
a re-branded web interface!

The edge of the Afrinic network is not the place to do this, not least
for the reason that the information visibility there will be dependent
on the routing policies of Afrinic's peers and transits.

A couple of safeguards might be sensible (although, for me, they should
not be blockers to the routing policy change):

- A UI warning could be provided if a member is about to create a ROA
that would kick them out of MyAfrinic
- A member's MyAfrinic IP whitelist (these are supported, I think?) must
contain a network not covered by a ROA issued by the same member
