In terms of what is "accepted" football-wise, people are obviously more lenient towards a foul then something that's more obvious - such as a dive.Every foul is technically cheating if you want to see it like that
I mean if we boil it down there's no difference between that and trying to claim a throw-in when you know you touched it last... it's all "cheating" (in football terms), but different forms of "cheating" are obviously treated with more disdain.
