Idk... If the tiny population of those bored "hobbyists" taking up space is the only reason a given route was overcrowded, I'd be surprised. If it's basically at capacity in general, I'd rather they add more busses than to crack down on the elderly, because I guarantee that if you just subtracted those "abusers" (and not elderly people who actually need to ride the bus for legitimate trips) the same bus would still be basically as crowded.
