Yes, I would ignore it, because whoever posted it is just looking for attention and I don’t want to fall into their trap. The only way I would respond is if I could somehow figure out that the post is a disguised cry for help. Usually those posts contain something about the poster’s own life (which may or may not be true or accurate).
Posting on this board that tznius no longer applies is the equivalent of posting a recipe for baked cat on a board for people who keep pet cats. In other words, it is trolling. Don’t feed the trolls!
