Well - In the case of windows phone I suspect no one particularly cared but couple of things for the (hopefully rare!) future instances of this happening.:
Could we have one last spam cleanup before the site is archived? While SE has very robust systems for this, some slips through
inIn addition to the A51 archives, would a archive.org or similar copy of the site aswhen it was in operation be possible?
What's the status of the site in data dumps and SEDE ? - will it simply cease to be and what's the period between sunsetting the site proper and removal from data query tools?
