Here in Spain shopping carts require a coin (normally 1 or 2 euro) to be taken. As a result, almost everyone leaves them at the cart racks (because they don't want to lose the coin). Having "scooter racks" that worked in a similar way could probably help, but then you'd need to walk to a nearby rack to get a scooter, increasing the probabilities of having to walk longer distances to get one.

When I parked my lime scooter the other day (before they were all removed from SF) it asked me to take a picture of the scooter to help others find it. I think a similar coin return situation (ie a small credit for their next ride or discount off of current ride) could be implemented with this picture taking. Show them where you parked and then if they can see that you parked it inappropriately they can start tracking bad actors and do something to intervene. This would most likely take the form of banning certain people by phone number or drivers license.
