This is what I have to tell people who make fun of the sport for all the flopping. Sure, it definitely is a problem and I hate when players do it - when I played unless you were seriously hurt you got back up and helped your team (or our coach would sub us out).

But if you don’t milk it, the ref won’t call it and continue playing even if it’s a foul. Damned if you do, damned if you don’t. Players who actually get up and continue don’t get the calls made against them.
