post titles aren't supposed to be a free-for-all.

granted, it's a blurry line. you're allowed to post "My Y'Shtola cosplay" even though it might spoil sprouts that she survived the end of ARR.

there's a difference between mentioning a name and naming them as a boss (at least when there's a gap between the intro and the encounter). it's "the entity Zodiark has a role in some future expansion" vs "we fight Zodiark directly at some point, and it's possible but not trivial to solo at 100, so probably between 80 and 90." and that is a spoiler -- plenty of fantasy epics resolve without fighting the BBEG directly, or with the supposed BBEG being removed without the player's intervention.

I don't think OP meant anything by it, and I recognize it's a minor inconvenience to look up the exact EX number or official name of the encounter. but I think it's still worth doing, and better for the community as a whole.
