If you get to the platform, the train arrives as you get there, you have no time to use the ticket machine (or as is so often the case it's out of order anyway), you get on the train, intending to pay the conductor, there's no conductor so you intend to pay as you get off. This happens to me all the time and I have never had a problem. They just seem to randomly target people now and again to make examples of them.
