It's official: It's one of the worst excuses ever used.
If you ever feel bored, GO DO SOMETHING ELSE.
Don't just post something stupid on the forums when you're bored, find something else to do. Play a game. Draw something. Go outside if you're like that.
If you posted something because you're bored, at least don't say it. It's better when people can at least think that you had some purpose in posting what you did.
