Duolingo, the language-learning platform is more than just a beneficial tool for those wanting to learn a new language. It also has become popular with language aficionados. However, regrettably, it seems that even this popular platform also falls victim to the notorious Rule 34 principle.
Many have found that Duolingo + Rule 34 union exist out there. It may come as a surprise, but evidently, there are indeed user-generated artwork based on figures from Duolingo that follow the infamous principle that states "if it exists, there is porn of it."
