This topic is beating a dead horse, it's been one of the most discussed topics since I can remember. I'm fairly certain we haven't had an official response from SE on it yet, though.

That being said, a 24-hour lockout from everything on DF is laughable and makes it seem like you're just speaking out of anger, not with your head. I hope you aren't actually serious.

At most, I think a 2 hour lockout from that specific dungeon would be sufficient.
