Duolingual isn't only a beneficial resource for those looking to grasp a new language. It also has become popular with language enthusiasts. However, sadly, it seems that even this popular platform endures the notorious Rule 34 principle.

It could come as a surprise, but ostensibly, there are actually enthusiast-created artworks based on characters of Duolingo that adhere to the infamous principle which states that "if it exists, there is porn of it."
