Honestly, it's a rather dark and niche area of fanfiction. One possible scenario in these fanfictions could be that Naruto is framed by a powerful and shadowy organization within the Naruto universe. They manage to manipulate evidence to make it seem like he's a threat. As for the torture, it could be in the form of being experimented on with some sort of forbidden jutsu, which is a very different take from the usual Naruto story where he's the hero saving the day.
I'm not sure specifically which ones are the most popular. However, in general, these types of fanfictions might explore dark themes such as Naruto being wrongly accused and then facing various forms of torture. They often deviate from the original positive and heroic narrative of the Naruto series.
There could be many out there. Some might involve Naruto being framed by his enemies within the Hidden Leaf Village. For example, they could set him up to look like he's committed a serious crime against the village. Then, the torture part could be physical, like being put in a prison with harsh conditions, or mental, such as being isolated and having his friends turn against him because of the false accusations.
Well, it could be for creative exploration. The original Naruto story has a lot of positive and heroic elements. By writing about Naruto being framed and tortured, writers can add a new layer of complexity. They might be interested in exploring how the other characters in the Naruto universe would respond to such a situation. For example, would Sasuke still be so focused on his revenge if Naruto was in this kind of trouble? It also allows them to play with the power dynamics and politics within the village in a different way.
There are various 'Harry Framed' fanfictions out there. Some are set during his school years at Hogwarts, where the framing causes chaos within the school walls.

These stories often add new layers to the original Harry Potter universe, exploring different aspects of magic, politics, and relationships.
Well, in some 'tortured merlin fanfiction', Merlin is often put in situations where his loyalty is tested to the extreme.

Also, there are stories where Merlin's relationships, like with Arthur or Gaius, are strained due to misunderstandings that lead to his 'tortured' state.
