One possible scenario could be that Naruto is constantly taunted in the streets. The villagers might throw things at him or call him mean names, like 'demon brat'. Another could be that they exclude him from village activities, making him feel like an outcast.
Perhaps the villagers would vandalize Naruto's living quarters. They could break his windows or paint mean things on his door. Socially, they might also get the local merchants to refuse to serve him. This would make it extremely difficult for Naruto to get basic necessities. It's a really sad situation for him in this fanfiction, but it also sets up a lot of potential for character development as he tries to overcome this abuse.
At first, Naruto might be very sad and confused. He doesn't understand why the villagers are treating him so badly.
Well, in some fanfictions of this kind, Naruto could be tortured physically by being chained up and beaten. His captors might also starve him or deprive him of water to weaken him.
