Been (and kind of still am) a bit ill over the past few days so haven't had the energy to answer PMs.
Since my memory is shaky when it comes to most moderated content and there are several active global mods moderating the forum, I can neither confirm or deny I deleted the post. I did go through the report logs and while someone did report your post (and it's marked as handled), it seems like not only your post, but the entire thread was deleted alongside it. Not sure how post notifications work when a thread is deleted instead of trashed but maybe it's sent out on thread deletion (=/= thread trashing) as well. The thread you're linking to is a newer one.
Also, seems like whoever handled the report, marked a duplicate report from a user as valid, which makes me believe I wasn't the one who deleted your post (I use a script that highlights duplicates) and AFAIK I haven't deleted (not trashed) any threads at least in the past week.
