Duolinger isn't only a beneficial tool for those wanting to learn a new language. It also has gained popularity among language hobbyists. However, unfortunately, it seems that even this popular platform endures the controversial Rule 34 principle.
Numerous individuals found that Duolingo® + Rule 34 fusion exist. It may come as a surprise, but evidently, there are actually user-generated artwork based on characters of Duolingo which abide by the infamous guideline stating that "if it exists, there is porn of it."
