How can we tell the difference between people who exploit OOS and people who legitimately lag out? (Sorry if that was a dumb question lol)
Lagging out looks different than OOSes, cause you get the you know, OOS screen.
But there are some cases in which OOSes are natural and unintended, in which case we see if it happens more than once, and when it happens. If it happens with a certain player many different times, and every single time he was on the losing end of a battle, then we can assume that the OOSes were forced.
