Kinda agree but it's not that hard to just post in the spoiler topics and make threads with [spoiler] in the title. It's not hard labor. Just courtesy for those who wish to be surprised.
I do however think it's a big extreme having things like
edited in a thread title and replaced with [spoiler], since it doesn't give away the name, age, location, lifestyle or personality of a housemate.
But like I say, it's easy to post in the spoiler topics. Not like the forum experience is being ruined.
