It is different to waving a card though, isn't it.
If you put your hands in the air when you think it's your teams throw in, technically thats influencing the referee, no one will complain about that. Whats the difference between claiming a throw in, and claiming a foul?
i've stated that players influence the referee and it wont be the last time it happens. but influencing a throw in and getting a player sent off are a little different, unless you're playing stoke!
