It can happen rarely in cases of some crazy workouts
If anyone's curious about why:
Muscles break down during workouts. They release myoglobin, which is a large protein. The kidneys can usually filter it in small quantities.
If you go too hard and give yourself rhabdomyolysis, your body releases a large quantity of myoglobin and it overloads the kidneys. Large proteins begin passing through the nephrons en masse and damaging them because they're too big.
Now your kidneys are unable to filter properly because the nephrons cannot contract to prevent excess fluids or particles from going into your urine.
GeoIP restricting is a brilliant idea I never thought of. I have been getting a few people trying to sign up on one of my other services and they're all from Asia somewhere.
