If it exists there is of it
Duolingo is not just a beneficial tool for those wanting to acquire a new language. It also has gained popularity among language aficionados. However, unfortunately, it seems that even this popular platform also falls victim to the controversial Rule 34 principle.
Many have discovered that Duolingo™ + Rule 34 union exist out there. It might come as a surprise, but ostensibly, there are actually enthusiast-created artworks based on characters of Duolingo which abide by the infamous guideline that states "if it exists, there is porn of it."
