A little more time to review would have been helpful but regardless, I think you've got most of items 1.b and 1.c totally backwards. TO suggest new registrations of expired domains are in scope of name collisions surprises me, and that bit flips or other things
that may result in persistent collisions are out of scope seems to ignore the immense amount of SSAC work that led to this WP. I think perhaps both may be out of scope but where you arrived with expired domains being re-registered as in scope confuses me,
can you explain the genesis of that in any dialog we've had or in the SSAC direction provided?<br class="">

<div class="">I drafted this text based on extensive discussion in the SSAC WP that was set up before this project was opened up. It was presented on at two ICANN meetings (as well as multiple SSAC meetings) and referenced in two discussion group meetings
as well as being circulated to the list. No it is not backwards, it is exactly as agreed through that process.</div>
<div class=""><br class="">
</div>
<div class="">The original SSAC WP consensus on this included the recommended advice to give, which is basically "this happens all the time in the DNS, there are other policies that might be applicable but that’s not for us to say". We can agree the exact
text later.</div>

Apologies to both, I now recall that the disclaimer satisfied my previous objections (i.e., "In scope but will be addressed with general advice and not subject of data studies.")<br class="">

That said, IF things in the documents we post for comment are prohibited and off-limits for comment let's quarantine them and convey as such, else you'll see my insanity ensue... :-P<br class="">
