I have no clue why that thread is deleted. Possibly a mistake?
cc @ph00lt0 (might be keeping a closer eye on these things than I do)
edit: It seems like the OP deleted their entire account, which would indeed make this thread disappear. This is non-standard, usually people do not request also deleting all their posts when they delete their profiles, but we do honor those requests. This destructive behavior is why I do not allow people who delete all their posts to return to this forum, it’s rude
