In such a fanfiction, it could be that Issei is bashed because he represents a different kind of hero compared to what Naruto stands for. Naruto is all about self - sacrifice and believing in others no matter what, while Issei is more about his own desires and power - seeking in a way. So when these two worlds collide in the fanfic, Issei might be made to look bad in comparison. Maybe the story has Naruto characters like Sasuke or Kakashi giving Issei a hard time because they don't approve of his behavior.
Perhaps the plot revolves around a conflict between the ideals of the Naruto world and Issei's actions in Highschool DxD. The Naruto characters, with their strong sense of justice and camaraderie, see Issei as a threat to the harmony of the new world they find themselves in. So they begin a sort of campaign against Issei. This could involve things like trying to expose his wrongdoings to the other characters in the Highschool DxD world, and at the same time, using their own powers and skills to undermine Issei's position in the school and in the supernatural hierarchy.

It could also be about changing the overall tone of the story. Instead of Issei's more comical and pervy attitude driving parts of the plot, the fanfiction might have a more serious or different comical approach by removing or reducing his presence.
