This is not a question, since I don't expect you'd be able to answer it--not in connection with that situation anyway. But it occurs to me that
if destroyed accounts support annotations (mod-only information on a profile, a feature I have read of on
Meta Stack Exchange) then it might be good to annotate any account that was destroyed appropriately but under circumstances that might later appear to have been a mistake. (But maybe it already was, or maybe the feature was unavailable in this context.)
