I'm not sure but I've noticed similar behaviours in others. I think it is due to the random reward of getting an item when you swipe a few times in the facebook app: people become absorbed in it the same way they become absorbed in gambling terminals, and crucially it is the same mechanism of reward. It might be worth considering what interventions people make with problem gamblers. I suspect if those interventions would work for people in your situation too.
