No really, the reason for some leaks isn't because so-and-so was
never a customer, they were. 5 years ago. nobody removed the routes from
the IRR or AS-SET or <insert method here> and now the route is learned via
some other location and it's bypassed your perimiter security and
infiltrated your BGP.

I agree, how many of you folks that use IRRs have ever deleted an IRR object? Heck, some ISPs even add them based on existence of advertised routes.
