If it's not a dive it's still unsporting to turn around towards the ref and "ask" for a penalty.
agreed but under the current rules it would be moronic not to as you won't ever get penalised for it
either the ref gives the foul in which case he's expecting you to appeal or he gives it as a dive in which case you get done for simulation, part of the simulation being the appeal
either way your unsporting penalty appeals will always go unpunished
