Subtlety is definitely key - I think blatant uncreative coming out of the closet statuses are kinda lame and the only people who take them seriously are old people who don't understand... maybe I'm just of this mindset because there was a stage when a few of my friends had their facebooks hijacked at least twice a week to the extent that it's become a massive game and they've honed their hijacking/trolling skills beyond belief.
I think one exception to this was when one of my flatmates hijacked my fb to announce in the plainest way possible that another of my flatmates is g
ay (___ is g
ay) and it led to a 30 comment status
